Post‐doc Position Defect characterization of compactified nanoporous…

TU Wien is located in the heart of Europe, in a cosmopolitan city of great cultural diversity. Our identity as a research university means that we build our reputation through our research. TU Wien combines basic and applied research and research‐oriented teaching at the highest level.

The group of Prof. Ulrich Schmid at the Institute of Sensor and Actuator Systems invites applications for a 2‐year Post‐doc position (starting January, 2023) in the field of defect characterization of compactified nano‐porous silicon carbide (4H‐SiC).

Due to outstanding properties in comparison to silicon such as a large bandgap ensuring a high electric breakdown strength and a high thermal conductivity silicon carbide (SiC) is regarded as one of the most promising wide band gap semiconductors for future high power and high frequency electronic applications. Besides these well‐known material parameters, advanced device architectures request novel approaches for fabrication. In recent years, photoelectrochemically porosified SiC emerged as promising technology to integrate optical elements (e.g. Rugate mirror) into single‐crystalline SiC and to realize robust MEMS devices (e.g. membranes) in a tailored surface micromachining process. Furthermore, the surface to volume ratio could be increased for chemical sensor applications as well as the realization of membranes lifted‐off from the SiC mother substrate was demonstrated.

Within the frame of an interdisciplinary research project, including 9 researchers and two company partners, it is our goal to exploit the full potential of photoelectrochemically porosified SiC layers, by establishing a fundamental understanding in the formation of electrically active defects and their impact on the performance of power devices and MEMS.

The post‐doc will provide deep insights in the electrical, structural as well as chemical properties of photoelectrochemically porosified SiC layers before and after compactification. He or she will support the principal investigator of the project, Dr. Georg Pfusterschmied in the supervision of PhD students employed in the project and will assist in the coordination of daily tasks as well as the knowledge exchange with the company partners. The post‐doc will also support the PhD students in structural and chemical analysis.

For more information about the project please contact the principal investigator (PI) Dr. Georg Pfusterschmied ([email protected] ).

We invite highly qualified and motivated researchers with a PhD having a strong interest in defect characterization of compactified nano‐porous 4H‐SiC layers to send us your detailed application documents (including a letter of motivation and CV) in a single pdf file via email to [email protected]  until December 11th, 2022

Candidates are not eligible for a refund of expenses for travelling and lodging related to the application process. TU Wien intends to increase the number of women on its faculty and therefore specifically invites applications by women. Among equally qualified applicants, women will receive preferential consideration.
