The Semiconductor Spectroscopy and Devices group at the University of Strathclyde began its activities in 1987 as a wing of Professor Brian Henderson’s Solid State Materials Group. It became a separate entity in 1990 with a mission “to explore the optoelectronic device capabilities of less-well-developed semiconductors”: at first, visibly emitting semiconductor compounds from the Zn(Cd)S(Se) family.
Superlattices and quantum wells, including ZnSe-ZnS, CdSe-ZnSe, CdS-ZnS, CdSe-CdS (hex) and CdS-ZnSe (hex-cubic), have since been studied in detail.
In 1991, we began studies of the novel semiconductor porous silicon. Since 1993 magneto-optic studies of strained-layer III-V heterostructures have joined the list, and more recently (since 1995) we have worked on:
- gallium nitride (GaN)
- indium gallium nitride (InxGa1-xN)
- silicon quantum dots
- chalcopyrites (e.g. CuInSe2, Cu(In,Ga)Se2)
- zinc oxide (ZnO)
- cuprate superconductors
- dilute nitrides
- geological minerals (e.g. calcite, zircon)
- fossilised trilobite eyes
- metallic nanoparticles
- 9th century Chinese paper…
…in fact, just about anything that glows!
The group has hosted a number of national and international conferences, including:
- Nanolight13: Control and applications of light at the nanoscale, 2–3 September 2013
- 9th International Conference on Nitride Semiconductors (ICNS), 10–15 July 2011
- RMS Electron Backscatter Diffraction Conference, 3–4 April 2006
- 5th International Conference on the Physics of Light-Matter Coupling in Nanostructures (PLMCN-5), 8–11 June 2005
