Anorganische Chemie
The Fritz-Haber-Institut (Anorganische Chemie) offers a
  2 Postdoctoral
position(s).

The Fritz Haber Institute (Department of Inorganic Chemistry) offers

Postdoctoral positions for electron microscopy and X-ray microscopic investigations of functional materials.

Your tasks: The successful candidates will have the opportunity to gather experiences in different microscopic techniques for heterogeneous catalysis. In heterogeneous catalysis, the catalytic conversion happens at the surface of a solid and is influenced by the presence of defects. The local geometric and electronic contributions of these local alterations from the ideal structure are difficult to describe by common surface and bulk averaging methods.

In addition, the electronic and geometric structure of solid catalysts in their active states dynamically responds to the applied chemical potential of the gaseous environment. To conclude on relevant morphological and electronic changes structural dynamics have to be tracked in-situ.

The successful candidates will, therefore, work on unraveling surface termination, and defect structures at highest resolution and will use different quasi in-situ and in-situ microscopic techniques to track catalysis induced changes. The applied analytical portfolio ranges from bright field TEM, STEM with different detectors, over EELS/EDX to X-ray microscopy.

The outcome of the projects will directly contribute to the establishment of new structure-activity correlations of heterogeneous catalysts, which will provide new insights into heterogeneous catalysis.

Your profile: We are looking for highly motivated scientists with conceptual skills, who can work independently, and are able to adopt new methods quickly. Required qualifications include a PhD in chemistry, materials science, or physics. A strong proven research background in electron microscopy or X-ray microscopy is mandatory. In addition, knowledge in heterogeneous catalysis is advantageous.

We offer: The postdoctoral positions will be for 2 years with the option on extension and the opportunity for further qualification. The successful candidates will work with state-of-the-art aberration corrected electron microscopes, X-ray microscopes and in-situ equipment.

Physikalische Chemie
The Fritz-Haber-Institut (Physikalische Chemie) offers a
  PhD-position
position(s).

The Fritz Haber Institute (Department of Physical Chemistry) offers a

PhD-position for Charge Transport at the Single-Molecule Level .

Research background: The functional units in organic devices can be synthesized with atomic precision. The resulting miniaturization of the integrated circuit leads to an improved performance and power consumption. Key to the development of organic devices is a profound understanding of the charge transport on a single molecular level. Scanning probe microscopy (SPM) became a powerful tool for the investigation of nanostructures as well as for single molecules, the core of organic devices. Recent experiments confirmed that the environment, the conformation and the coupling of molecular wire have a strong influence on its charge transport properties.

Your tasks: We will develop a new silicon sample architecture for SPM that hosts an integrated circuit. In contrast to molecular break junction and SPM pulling experiments, the adsorption geometry and position of the molecules can be fully characterized by SPM imaging while studying their electrical properties. These novel samples are developed at the NPZ clean room facilities of the TU-Berlin. In a next step we want to extend the integrated circuit to nanoscopic contact patches with scanning tunneling hydrogen resist lithography. This allows us to fabricate electrodes which are as small as two atomic rows and which act as gate, source or drain in single-molecule transport measurements.

This setup is unique because the SPM tip can characterize the molecular junction with sub-molecular resolution. Further, we can position individual molecules with nm precision by SPM manipulation and most importantly, the SPM tip can act as an additional electrode which can be placed with Angstrom precision. This combination of SPM imaging, SPM manipulation and transport measurements allows us not only to tune the junction but also to correlate the measurement signals to the precise chemical composition of the junction.

Your profile: Potential PhD students should have a background in physics or related subject, solid-state physics, low temperature scanning probe microscopy and/or device fabrication.

Your application: To apply please send a letter of motivation, a CV and your two most relevant publications preferred by email to

Anorganische Chemie
The Fritz-Haber-Institut (Anorganische Chemie) offers a
  Postdoctoral
position(s).

The Fritz-Haber-Institut (Anorganische Chemie) offers a Postdoctoral position in Raman spectroscopy.

Your tasks: The research involves studies of nanostructured solids by Raman spectroscopy applying varying excitation wavelengths. The materials of interest are oxides and metal nanoparticles used in heterogeneous catalysis and energy-related applications.

Complementary spectroscopic techniques, like UV-vis and photoluminescence spectroscopy should also be applied. The measurements will be performed under operation usually in gas-phase reactions at elevated temperatures. The functionality is proven by gas chromatography or mass spectrometry of the reaction products formed. Isotope exchange experiments will be used to support assignments of spectroscopic features.

The candidate will be involved in the collaboration of the Fritz-Haber-Institut with the UniCat BASF JointLab at the Technical University Berlin within the framework of the project “Selective oxidation of alkanes”.

Your profile: The eligible candidate is highly motivated, ambitious, works independently and well in a team. Effective communication and writing skills are essential.

Physikalische Chemie
The Fritz-Haber-Institut (Physikalische Chemie) offers a
  MS Project on the topic *Building a New Light Source for Surface Specific Vibrational Spectroscopy*
position(s).

The ability to generate femtosecond duration continuum light sources is revolutionising vibrational spectroscopy: we are just entering an era in which the possibility of characterising the entire vibrational spectrum with femtosecond time resolution is possible. However, to this point, the application of such sources to surface-specific nonlinear optical probing techniques has lagged, principally because of the high pulse energies such methods generally require. Much effort has been expended over the last 3 years developing such sources for applications other types of experiments in solid-state and AMO physics. The Interfacial Molecular Spectroscopy Group in the Physical Chemistry Department at the Fritz Haber Institute seeks a motivated MS student to optimise such a source for application to surface-specific vibrational spectroscopy. The ideal student should have a background in Physics, Photonics, Electrical Engineering or Physical Chemistry. Requests for additional information and applications should be sent to Dr. Martin Thaemer (thaemer@fhi-berlin.mpg.de, subject: Continuum-MS) in a single pdf with the following materials:

> 1. Letter of motivation explaining why you find this project interesting.
> 2. Certificates showing your academic record including results on a per course basis.
> 3. CV showing any previous relevant experience: particularly prior research internships.

  Multiple PhD and Post-doctoral
position(s).

Multiple PhD and Post-doctoral positions on the topic *Understanding Electron Transfer Across Solid/Liquid Water Interfaces*

From a microscopic perspective all aqueous (photo)electrochemistry involves similar physics: electrons move between a solid electrode and an aqueous electrolyte and in so doing induce chemical change. As part of a recently funded ERC Consolidator Grant the *Interfacial Molecular Spectroscopy Group* seeks multiple PhD students/post-doctoral researchers to experimentally characterise the chemistry of water splitting in several systems by watching electron transfer between solids and liquid water, and correlated chemical change, with femtosecond time resolution. The work will require the development and application of novel nonlinear optical probing techniques, as well as more conventional (photo)electrochemical characterisation. The program is embedded in the Physical Chemistry Department of the Fritz Haber Institute of the Max Planck Society in Berlin, Germany. The department is a world leading location for the study of ultrafast dynamics in solids using photon and electron based techniques. Beyond the department the Fritz Haber Institute has a storied history, and much important ongoing work, in the study of heterogeneous chemistry in general and (electro)catalysis in particular. The envisioned work strongly benefits from both strands of these ongoing activities. Requests for additional information should be sent to Dr. R. Kramer Campen (campen@fhi-berlin.mpg.de). Applications will be accepted until positions are filled.

Potential post-docs should have a background in either(photo)electrochemistry or femtosecond optical spectroscopy and be fluent in written and spoken English.

  PhD
position(s).

Development of a narrowband XUV source

The Emmy Noether research group Dynamics of Correlated Materials at the Fritz Haber Institute (http://www.fhi-berlin.mpg.de/pc/docm-new.html) is offering a PhD position in experimental condensed matter physics and laser development. The group investigates the ultrafast dynamical processes in strongly correlated systems, in order to understand the manifold of competing broken-symmetry ground states of those materials such as high-temperature superconductivity, magnetic orders or density wave formation. The Fritz Haber Institute and the department of physical chemistry offer an excellent and interdisciplinary environment for top-of-the-line research. The group operates and further develops a world-leading high repetition rate extreme ultraviolet (XUV) time- and angle-resolved photoelectron spectroscopy (trARPES) setup based on a high-power all fiber-driven OPCPA laser system.

Topic of the doctoral thesis: Development of a narrow-band high-repetition rate high harmonics generation (HHG) XUV light source for time-resolved ARPES experiments in unconventional superconductors. The successful applicant will construct and build a novel narrow-band XUV source for trARPES with high energy resolution, which will be complementary to the existing HHG setup that is optimized for high temporal resolution. This HHG source will be then used to investigate the ultrafast dynamics in strongly correlated materials exhibiting ordering phenomena at small energy scales such as high-temperature superconducting Cuprates and Fe pnictides, antiferromagnetic or heavy-Fermion Kondo systems.

Applicants should hold an excellent Diploma or Master degree in Physics or Material Sciences, and should have a strong background and interest in at least one of the following areas:

- ultrafast laser development and technology
- pulse shaping and compression
- high-harmonic generation
- femtosecond time-resolved spectroscopies
- photoelectron spectroscopy
- physics of strongly correlated materials

The appointment will be for a duration of 36 months and the initial salary will be oriented at the TVöD (E13, 60%) with the potential for performance-related raises (up to 75%). Preference will be given to female and handicapped applicants provided equal suitability. Applications (motivation letter, CV, list of publications, description of previous work, contact details of at least two academic references, etc.) shall be sent to:

The Fritz-Haber-Institut (Physikalische Chemie) offers a
  Two PhD
position(s).

The Emmy Noether Research Group Dynamics of Correlated Materials at the Fritz-Haber-Institute is offering two PhD positions in experimental condensed matter physics. The group investigates the ultrafast dynamical processes in strongly correlated systems, in order to understand the manifold of competing broken symmetry ground states of those materials such as high-temperature superconductivity, magnetic orders or density wave formation. The Fritz Haber Institute and the Department of Physical Chemistry offer an excellent and interdisciplinary environment for top-of-the-line research.T he group operates a world-leading high-repetition rate extreme ultraviolet (XUV) time- and angle-resolved photoelectron spectroscopy (trARPES) setup and performs time-resolved x-ray diffraction experiments at large scale research facilities.

Topics of the research: Both offered positions concentrate on the femtosecond dynamics of phase transitions in strongly correlated materials, which arise due to the strong interplay of electronic, lattice and spin degrees of freedoms. By employing a combination of complementary time-resolved techniques sensitive to the respective degrees of freedom those couplings will be directly assessed in the time-domain. The first position will concentrate the electronphonon coupling in model systems exhibiting metal-insulator transitions induced by charge density wave order, while the second position will investigate the interplay of electronic correlations and magnetic ordering in various classes of antiferromagnetic model systems, which hold a strong relevance for future spintronic applications. The experiments include femtosecond XUV trARPES measurements, giving access to electron dynamics, and complementary information on spin and lattice ordering will be gained from time-resolved (resonant) x-ray diffraction experiments performed at synchrotron and/or free-electron laser facilities. Additional ultrafast electron diffraction experiments can be performed in collaboration with the Structural & Electron Surface Dynamics group at the FHI. Sample preparation will include in-situ growth as well as sample cleaving in UHV chambers.

Applicants should hold an excellent Diploma or Master degree in Physics or Material Sciences, and should have a strong background and interest in at least one of the following areas:
- femtosecond time-resolved spectroscopies
- photoelectron spectroscopy
- x-ray or electron diffraction
- in-situ growth of epitaxial metal and oxide films in ultrahigh vacuum
- physics of strongly correlated materials

Both appointments will be for a duration of 36 months and initial salary is according to TVöD-L (E13, 60 percent), with the potential for a performance-related raise up to 75 percent). Preference will be given to female or handicapped applicants provided equal suitability.

Physikalische Chemie
The Fritz-Haber-Institut (Physikalische Chemie) offers a
  PhD position in “Terahertz spintronics”
position(s).

The project: Terahertz spintronics

Currently, many research efforts aim at extending conventional electronics (which is based on the charge of the electron) by the electron’s spin degree of freedom. Elementary operations of such spin-based electronics (spintronics) are the reorientation and transport of spins in space. They should proceed as fast as possible.

The goal of this project is to measure, understand and finally control spin dynamics in solids at extremely high, that is, terahertz frequencies. In the course of this work, stimuli and probes based on terahertz electromagnetic transients and femtosecond laser pulses will be developed. New applications will emerge, e.g. efficient broadband emitters of terahertz radiation.

You have
• An excellent master’s degree in physics or related subject
• Background in solid-state physics (e.g. magnetism) and/or ultrafast laser spectroscopy

You get
• Exciting research in a dynamic Max Planck group located in the Berlin science area
• Excellent supervision and education, including the International Max Planck Research School

How to apply? Please mail us
• Your scientific CV and university certificates with marks
• A motivation letter (max. 1 page) why you want to join the group. Only applications with this motivation will receive our full attention.

The Terahertz Physics Group
• Makes use of cutting-edge ultrafast terahertz technology to reveal and control new ultrafast processes in condensed matter
• Develops novel schemes for the efficient generation, detection and manipulation of electromagnetic pulses in the highly unexplored terahertz frequency window

Molekülphysik
The Fritz-Haber-Institut (Molekülphysik) offers a
  Diploma/Masters and PhD
position(s).

A diploma, masters and Ph.D. position is available in the Molecular Physics department at the Fritz Haber Institute of the Max Planck Society (FHI) in Berlin, Germany. The project is focussed on the analysis of protein glycosylation using the promising technique of ion mobility spectrometry.

Glycosylation is one of the most abundant types of post-translational modifications found in proteins. The involved oligosaccharides are termed glycans and usually exhibit a branched and stereochemically complex structure. Currently, glycans are typically characterized using mass spectrometry-based techniques (MS). Measuring the molecular weight of a sugar, however, immediately poses a fundamental problem: entire classes of the constituting monosaccharide building blocks exhibit an identical atomic composition and, consequently, also an identical mass. Therefore, carbohydrate MS data can be highly ambiguous and often it is simply not possible to clearly assign a particular molecular structure. Within this project a novel, interdisciplinary approach to characterize complex sugars by incorporating ion mobility spectrometry as an additional gas-phase separation dimension should be developed and applied. Experimentally, this involves a variety of biochemical and bioanalytical techniques such as the enzymatic cleavage of the sugar form the investigated gycoprotein, the instrumental analysis using a commercially available, hybrid ion mobility mass spectrometer as well as the analysis of complex datasets using in-house developed software tools.

The applicant should have a background in biochemistry, (bio)organic chemistry and/or analytical chemistry. Basic experience with chromatographic separation techniques as well as mass spectrometry-based techniques would be helpful, but is not required.

The Fritz-Haber-Institut (Molekülphysik) offers a
  Ph.D. and Postdoctoral
position(s).

A Ph.D. and/or postdoctoral position is available in the molecular physics department at the Fritz-Haber-Institut der Max-Planck-Gesellschaft (FHI) in Berlin, Germany. The research involves spectroscopic studies of mass/charge selected (bio-)molecules using the FHI infrared free electron laser. The data is used to gain fundamental insight into the structure, and function of biological molecules and their aggregates. In one experiment, those (bio-)molecular ions are incorporated in ultracold liquid helium droplets, which allows for measuring IR spectra at high resolution (see for example Phys.Chem.Chem.Phys., 17, 21902 (2015)). In a different experiment, in addition to mass/charge selection, conformer selection is performed using ion mobility methods. This allows for the recording of IR spectra of species that have the same mass/charge ratio, but differ in conformation, protonation site or aggregation state (see for example J. Am. Chem. Soc., 137, 4236 (2015)).

Requirements:
- degree in physical chemistry, experimental physics or related fields
- experience in laser spectroscopy on gas phase molecules, gas-phase molecular beam methods and/or mass-spectrometry (required for the post-doctoral and desired for the graduate student position)

Please arrange for two letters of recommendation together with the application.

Molekülphysik
The Fritz-Haber-Institut (Molekülphysik) offers a
  PhD
position(s).

The Research Group "Interactions of molecules with fields" headed by Bretislav Friedrich has a PhD position available in theoretical molecular physics.

Topic: Supersymmetry and entanglement of polar paramagnetic molecules subject to combined electric, magnetic, and optical fields.

Description: Polar paramagnetic molecules are of potential importance for many-body physics simulations, studies of crossings of eigenenergy levels, and quantum information and computing. Based on our previous work, we plan to study the supersymmetry and entanglement of polar paramagnetic molecules in the triple-combination of electric, magnetic and optical fields. The triple field combination not only offers a high efficiency and flexibility in manipulating molecular rotation and translation but is also of fundamental theoretical interest per se, as monodromy and quantum chaos lurk behind the combined-field effects. The research will deal with key aspects of the interactions of polar paramagnetic molecules with and in the combined fields: their supersymmetry and entanglement. While supersymmetry provides an in-depth insight into the nature of a system and may yield analytic solutions for a class of its eigenstates, entanglement sheds light on the nature of the many-body interactions that arise within the quantum system. For more, see http://www.fhi-berlin.mpg.de/mp/friedrich/program1.html.

Funding: The position is funded by a grant from the Deutsche Forschungsgemeinschaft.
