The department Microstructure and residual stress analysis is looking for:
PhD Student (f/m), Master or equivalent degree in Physics or Material ScienceReference No.: EM 2017/17
Topic of the doctoral thesis:
Real-time growth analysis and modelling of chalcogenide semiconductor thin films with increased bandgap
The research of the department is focused on the characterization of structure and properties of materials on different length scales. Advanced diffraction and scattering methods are used for nano- and microstructure as well as time resolved studies, applied to a wide spectrum of materials ranging from photovoltaics, proton and oxygen conducting materials, and battery materials. Currently, we are taking into operation a new lab dedicated to real-time and in-situ film growth studies, equipped with a high brilliance metal jet x-ray source.
Focus of the PhD thesis is to study the influence of growth conditions of thin film semiconductors for solar cells with increased band gap on their microstructural and physical properties. For this, solid state reactions are studied in real time X-ray diffraction, fluorescence analysis and white light scattering. Complementary, model calculations by means of reaction-diffusion equations will be employed to gain detailed insights into the physical and chemical mechanisms taking place during the reactions.
- Fundamental research of the reaction-diffusion mechanisms in Cu(In,Ga)Se2 semiconductor films and related materials
- Numerical data evaluation and modelling
- Synthesis and characterization of semiconductor films with increased bandgap
- Presentation of results at project meetings and international conferences
- Publication of research results in scientific journals and writing a PhD thesis
- University degree in Physics, Material Science or similar
- Knowledge in solid state physics or chemistry as well as skills in programming is desired
- High motivation and creativity
- Good communication and English skills
