Vibrational Studies of Magnetite and Silicon Dioxide Model Catalyst Systems

The Fritz Haber Institute (Chemical Physics Department) offers a PhD or PostDoc position

Project:
The activities of the Chemical Physics Department are centered around the investigation of catalytic processes on well-defined surfaces. In this scientific area we offer a position for studies of gas-surface interactions with electron-based vibrational spectroscopy (HREELS). Studies of the hydroxylation of thin SiO2 layers, the effect of the modification of SiO2 by metals like chromium or iron on the surface reactivity, the activation of carbon dioxide on ordered magnetite surfaces and the effect of water/hydroxyls are part of the project.

CO2 is a common end product of many reactions and a relevant greenhouse gas. It is available in large amounts but not very useful from a chemical point of view. Therefore there are ongoing efforts to find ways to convert this gas into higher valued chemicals. One aim of the project is the exploration of the activity of iron oxide surfaces, namely the (100) and (111) magnetite surfaces, towards the chemical activation of carbon dioxide using electron-based vibrational spectroscopy.

Amorphous and crystalline SiO2 layers are models for SiO2 supports in catalysts systems. Such supports are usually hydroxylated which affects reactions at the surface. The investigation of the interaction with water including the effect of doping is another aspect of the planned work.

Scientific environment:
The central investigation theme of the Chemical Physics Department is catalysis on well-defined surfaces with the goal to understand the underlying processes on a microscopic level. You will find a technically well-equipped environment with an international staff working on a manifold of projects in the area of catalytic surface reactions.

Requirements:
The applicant should hold a master or PhD degree in physics or chemistry. Experience in vacuum technology and methods for surface investigation is mandatory for PostDoc applicants and desirable but not required for PhD applicants.

Chemische Physik
The Fritz-Haber-Institut (Chemische Physik) offers a
  Postdoc position in High-Field Electron Paramagnetic Resonance (EPR) spectroscopy on single crystal surfaces
position(s).

The project focuses on the investigation of paramagnetic centers on well-defined model catalysts. The properties of these centers will be investigated using a unique instrument, which allows EPR spectroscopy at 94 GHz of single crystal surfaces under ultra-high vacuum conditions.[1] Defects play an important role for understanding the physical and chemical properties of surfaces. Despite the large toolbox of surface science a thorough characterization of defects with respect to their structural, electronic properties as well as their impact on the chemical characteristics remains challenging. To this end EPR spectroscopy has been proven be a particularly powerful tool to unravel electronic as well as structural properties of paramagnetic centers on surfaces.[2] In the present setup, the information obtained by EPR spectroscopy can be supplemented by in-situ LEED, TPD, IRAS and STM measurements within the same apparatus, which allows for a comprehensive characterization of the system under investigation. The project aims at a detailed characterization of paramagnetic defects on single crystalline, thin oxide films grown on metal single crystal surfaces and their interaction with molecules as well as metal deposits introduced from the gas phase.

The applicant should hold a PhD in chemistry or physics and has to have a strong background either in EPR instrumentation or surface science. The position is immediately available. Applicants should submit (via email) an application letter stating their motivation in this work together with a detailed CV, a copy of the masters/diploma certificate (including grades), a copy of the PhD certificate, two names of possible reviewers, and a publication list.

The Max Planck Society wishes to increase the participation of women in its research activities. Therefore applications from women are particularly welcome. Handicapped individuals are especially encouraged to apply. Their applications will be preferred in case of equivalent suitability.

  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

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

The Dynamics of Correlated Materials research group at the Fritz-Haber-Institute is offering a PhD position. The group’s research focusses on the ultrafast electron dynamics after optical excitation in strongly correlated systems with their manifold of competing broken-symmetry ground states such as high-temperature superconductivity, magnetic orders or density wave formation. The group operates a world-leading high-repetition rate extreme ultraviolet (XUV) time- and angle-resolved photoelectron spectroscopy (trARPES) setup.

This project is focused on the dynamics in strongly correlated antiferromagnetic systems. The successful candidate will investigate the interplay of electronic correlations and magnetic ordering phenomena in various classes of antiferromagnetic systems, which are of strong relevance for future spintronic applications. These systems will be studied by femtosecond trARPES experiments using the XUV trARPES setup, as well as static ARPES measurements using a lab-based high-resolution ARPES setup. The sample preparation will involve in-situ growth in ultrahigh vacuum systems. In addition, static and time-resolved resonant x-ray diffraction experiments at synchrotron and/or free-electron laser facilities are planned.

Applicants should hold a 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
- in-situ growth of epitaxial metal and oxide films in ultrahigh-vacuum
- physics of strongly correlated materials

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.

Molekülphysik
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.

Please contact Gert von Helden, Ph.D., (helden@fhi-berlin.mpg.de) for further information.

"Low-Temperature Single Crystal Microcalorimetry/Molecular Beam Techniques for Probing Kinetics and Thermodynamics of Gas-Surface Interactions"

The project will focus on the investigation of interaction of gas phase molecules with well-defined nanostructured model supported catalysts. For this we apply a unique combination of low-temperature single crystal calorimetry and molecular beam methods under clean ultra-high vacuum conditions. The strength of interaction of gas phase molecules on surfaces is an important parameter governing the catalytic activity of heterogeneous catalysts. In this project, we focus on finding the correlations between the microscopic structure of the catalyst, its reactivity and heats of formation of the adsorbed reactants and the key reaction intermediates. As a catalyst, metal nanoparticles supported on planar thin oxide films prepared under well-defined UHV conditions are employed, whose structural properties can be tuned in a highly controlled manner.

A university degree in physics or physical chemistry is required. The position is immediately available. Applicants should submit (via email) an application letter stating their motivation in this work together with a detailed CV, a copy of the masters/diploma certificate (including grades), two names of possible reviewers, and a publication list.

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.

The Max Planck Society aims to increase the participation of women in research. Therefore, applications by women are particularly welcome. Handicapped individuals are especially encouraged to apply. These applicants will be given priority in the case of same qualifications.
