Prof. Sir Richard H Friend FRS, FREng

Biography

Richard Friend’s research explores the electronic properties of novel semiconductors, currently carbon-based organic semiconductors and metal halide perovskites. We use these as the active component in range of semiconductor devices, including photovoltaic diodes, FETs, and LEDs, both to study their fundamental electronic structure and also to explore applications in display technologies and solar cells.

Research

We have substantial facilities for the fabrication of thin film structures and active semiconductor devices, both using vacuum and solution-based processing methods. Besides our wide range of standard structural and optoelectronic characterisation techniques, we have a substantial investment in ultra-fast optical spectroscopy, with time resolution down to 10 femtoseconds, that we use to track the time evolution of photoexcitations.
