The Graduate School "Materials for Solar Energy Conversion (MatSEC)" is looking for:

PhD Student (f/m)

Kennziffer: MatSEC 2016/7

MatSEC is a member of Dahlem Research School (DRS), which provides a structured graduate education at Freie University Berlin.
MatSEC combines experiment and theory in the areas of material science, crystallography, solid state physics, solid state chemistry, and scientific computing to develop structure-property relations which allow for the design of custom-made materials for solar energy conversion.

Topic of the doctoral thesis:
Nanostructured Group IV Materials for High Performance Thermoelectrics

SiGe alloys are currently the best performing materials for high temperature thermoelectric applications. The nanostructuring of these group IV materials is an approach that is currently being investigated as a means to further improve their device performance via suppression of phonon transport by surface scattering.


The research for this project will be centered on the synthesis of group IV nanomaterials, where the structure-property relationships of these nanomaterials will be investigated through a combination of structural, thermal, electronic, and morphological methods, including both lab-based and synchrotron-based techniques. The ultimate goal of this project is to develop a colloidal synthesis route for group IV nanomaterials with well-defined sizes and shapes with controlled alloy compositions or core-shell structures that will allow for the precise tailoring of materials properties.


HZB grants PhD scholarship for the development of qualified junior scientists. The Phd scholarship is limited to 3 years. The amount of the PhD scholarship complies with the valid PhD scholarship allowances of DFG.

We particularly welcome applications from women. Preference will be given to handicapped applicants provided equal suitability.
