The Semiconductor Spectroscopy and Devices research group is part of the Nanoscience division of the Department of Physics at the University of Strathclyde.

News PhD and Postdoctoral positions

9^th International Conference on Nitride Semiconductors was held in Glasgow, 10^th-15^th July 2011. See icns9.org for more details.

Research interests include:

• semiconductor materials issues
• spatially and spectrally resolved photo- and cathodoluminescence
• electron backscatter diffraction and electron channeling contrast imaging
• scanning probe microscopy
• optical properties of nanostructures.
• first principles and semi-empirical modelling

Programme of research: the group's work combines basic techniques of optical spectroscopy and spectroscopic imaging with the realisation of opto-electronic devices using 21st Century semiconductor materials.
