Biography

I have been in Glasgow since 1986 having previously worked in Cambridge University, Bell Laboratories, ETH-Zürich, Cornell University, and Ohio State University. I spent the academic year 1997–8 at the University of California at Santa Barbara and was on secondment with Freescale Semiconductor in East Kilbride from September–December 2004. My textbook on the physics of low-dimensional semiconductors is widely used and has been translated into Japanese. More recently I have written a textbook on the Texas Instruments MSP430 microcontroller, for which a second edition is in preparation.

Research Interests

My research interests cover a wide range of theoretical semiconductor physics, mainly centred around III–V heterostructures and MOSFETs. Here are some topics of recent interest.
•    Fundamental problems associated with elastic fields in pseudomorphic heterostructures – those made from materials with different lattice constants – and how the elastic fields can be measured and exploited
•    Transport of electrons through nanostructures, particularly the effects of disorder and unusual forms of scattering, such as resonant scattering from remote impurities.
•    Fluctuations in MOSFETs from the random position of impurities, oxide thickness fluctuations, gate edge roughness, non-uniform alloy composition…
•    Electrical impedance tomography, the theory of which may have application to fluctuations in circuits rather than individual devices

Expertise

•    Chartered Engineer
•    Accreditor for Institution of Engineering and Technology (IET)
•    Member of Engineering Professors’ Council
•    Curriculum Area Review Committees (CARGs) in Mathematics and in Science for the Scottish Curriculum for Excellence
