Sascha Feldmann

PhD Student

Photophysics of Novel Semiconductors


Sascha studied chemistry at the Universities of Heidelberg and Cambridge. After finishing his Master's thesis in the surface science group of Prof Petra Tegeder he returned to Cambridge for a PhD in physics within the optoelectronics group. He currently works with Dr Felix Deschler and Prof Sir Richard Friend on ultrafast carrier dynamics in perovskites and other novel semiconductors.

Research Interests

Hybrid Perovskites


Low-Dimensional Materials

Ultrafast Spectroscopy
