Piotr Wiśniewski, PhD Eng.

Research Assistant Professor / The head of SEMINSYS Department


In 2015 received MSc. Eng. degree in microelectronics, photonics, and nanotechnology from the Faculty of Electronics and Information Technology of the Warsaw University of Technology. In November 2020 defended his doctoral dissertation with honors at the Faculty of Electronics and Information Technology of the Warsaw University of Technology entitled "Modeling of the current-voltage characteristics of the TFET tunnel transistor". Associated with the CEZAMAT project since 2013, where he has been responsible for laboratories and research equipment. In 2013 completed a 6-month internship at the IMEC research center in Belgium, where was involved in developing plasma processes for the production of advanced CMOS systems. His research interests include physics, modeling, and technology of semiconductor devices for micro / nano-electronics, particularly devices using quantum-mechanical effects.
