Dr Daniel Wolverson
Profile
My research interests include the optical spectroscopy of semiconductors and, in particular, the use of Raman microscopy, magneto-Raman scattering and photomodulated reflectivity in order to investigate electronic states in semiconductor heterostructures based on both II-VI and III-V compound semiconductors. Samples are supplied for these studies by many academic and industrial groups world-wide and the phenomena investigated include the special properties of dilute magnetic semiconductors, the optimisation of the growth and doping of epilayers and the behaviour of carriers confined in low-dimensional structures and quantum dot systems. New projects involve the application of optically-detected spin-resonance and coherent spin-flip Raman scattering techniques in order to study the above phenomena.
