Inorganic Semiconductors Group

Intro graphicResearch interests

The Inorganic Semiconductors Group is active in a variety of topical areas in semiconductor physics, photonics and the control of interaction between light and matter. The activities encompass both fundamental and applied research, ranging from single quantum dot and single photon phenomena to quantum cascade and quantum dot laser physics and device physics. There are over 80 personnel active in Semiconductor research in Sheffield, making it one of the largest groupings in the UK.
