Master and Ph.D. Theses at IFP

The Institute for Solid State Physics (IFP) has many opportunities for master and Ph.D. theses. We can give you access to a wide spectrum of excellent experimental facilities, competent and intensive support by our scientific staff and technical infrastructure. If you are interested in a master or Ph.D thesis in one of the research areas of IFP please contact the head of the corresponding working group.

Currently, we are pursuing various experimental and theoretical projects related to the iron pnictide compounds, which represent a new class of superconductors. In this context we are offering various opportunities for master and Ph.D. thesis, as well asfor postdoctorate candidates interested in working in this field.

PhD-Position:
Thermodynamic investigations of pnictide superconductors

At the Institute for Solid-State Physics (IFP) at the Karlsruhe Institute of Technology (KIT) we are pursuing various experimental and theoretical projects related to the iron pnictide compounds, which represent a new class of superconductors. In this context we are offering various opportunities for diploma and Ph.D. thesis, as well as for postdoctorate candidates interested in working in this field. In particular, two Ph.D positions are available in connection to the Schwerpunktsprogramm (Priority Program) SPP 1458 "Hochtemperatursupraleitung in Eisenpniktiden" (High-temperature superconductivity in iron pnictides) funded by the Deutsche Forschungsgemeinschaft.

Job description:
She/he will work in the "New Materials, Transport, Thermodynamics, and Mesoscopics" group of the IFP, which is specialized in single-crystal growth of novel new materials and in high-resolution thermodynamic probes (thermal expansion and specific heat). The project will address the interplay between structural, magnetic and superconducting properties of the recently discovered iron-pnictide superconductors.

Qualification:
The successful applicant should hold a Masters (or equivalent) degree in physics or chemistry, should have a solid background in solid state physics and mathematics, good experimental skills, and a strong personal commitment to research. Experience in low temperature techniques, in sample preparation, with the PPMS and MPMS systems from Quantum Design, and in high-resolution dilatometry are beneficial.

Master Thesis/ PhD-Position:
Effect of strain and pressure on a 2D electron gas between oxide insulators

(a) Interfacial structure of CaCuO2 on NdO-terminated NdGaO3. (b) HAADF-STEM cross-sectional image of CaCuO2/NdGaO3 prepared by PLD. (c) Element sequence (intensity scan) along the dashed line in (b) before and after background subtraction.

In our group "Thin Films and Interfaces " of the Institute for Solid State Physics (IFP) at KIT Campus Nord we offer the opportunity for experimental master and Ph.D. theses.

Our group works on the preparation and characterization of thin films and interfaces with superconducting or magnetic properties. For the film preparation sputtering and laser ablation are used. The analysis of the films comprises surface morphology, crystallographic properties, microstructure, magnetism, electronic structure, and electronic transport. The investigations are performed in close cooperation with other groups of the institute and other institutes of KIT.

PhD-Position:
Fabrication and electronspectroscopic investigations of epitaxially strained ruthenate and cobaltate thin films

In the Electron Spectroscopy group of the Institute for Solid State Physics (IFP) at KIT Campus Nord we offer the opportunity of an experimental doctoral thesis on the preparation and spectroscopic investigation of distorted ruthenate and cobaltate thin films. The position will be supported by the German Science Foundation (DFG) within the research unit Quantum Phase Transitions (FOR 960).

The mission of the IFP is the investigation of new states of condensed matter. Focused on its mission, IFP employs a large variety of experimental research tools: Electronspectroscopy methods, neutron scattering and the ultrasensitive determination of thermodynamic properties such as specific heat and thermal expansion provide information on low-energy excitations and collective phenomena close to phase transitions.

Our Electron Spectroscopy group operates the soft x-ray beamline WERA at the synchrotron facility ANKA at KIT (Campus Nord). The experimental methods photoemission (PES) and near-edge x-ray absorbtion (NEXAFS) allow to investigate the occupied as well as the unoccupied electronic structure which provides insights on aspects such as orbital or band character and spin state. Performing NEXAFS in strong magnetic fields using circular polarisation of the incoming radiation, dichroic effects (SXMCD) can be observed which provide information on magnetism as well as spin and orbital moment of the specific atom sorts. Lateral distribution can be imaged by means of Photoemission Electron Microscopy (PEEM).

Job description:
Fabrication of epitaxially strained ruthenate and cobaltate thin films by pulsed laser ablation on single crystal substrates with different lattice mismatch. In-situ investigation of the electronic structure by means of NEXAFS, SXMCD, PES (and eventually PEEM) at the IFP-owned soft X-ray beamline at ANKA (KIT Campus Nord).

Qualification:
Complete university studies in physics, crystallography or a closely related subject with very good success. Vivid interest in solid state physics and experimental work. Proficiency and communication skills in the English language.
