Optical Spectroscopy Group

Department of Physics, University of Bath

UNDERGOING MAINTENANCE, 23/11/11 !

The Spectroscopy and Imaging Group forms part of the Department of Physics' Semiconductor Photonics and Plasmonics Group and consists of Professor J. John Davies, Dr. Daniel Wolverson, Dr. Lowenna Smith, Dr. Stephen Bingham, Ms Jamaree Amonkosolpan and Ms. Caity Rice. 

The research interests of the group include:

	Optical spectroscopy and magnetic resonance of semiconductors;
	Raman scattering and magneto-Raman scattering to investigate electronic states in semiconductor heterostructures based on both II-VI and III-V compound semiconductors;
	Magnetic semiconductors (most recently, carrying out X-ray MCD studies of magnetic ions in GaN at the ESRF, Grenoble)
	Magneto-optics of excitonic states in semiconductor quantum wells (£329K EPSRC grant announced in November 2006); see here for more scientific details;
	Electron spin resonance imaging for bio-medical applications (£854K BBSRC grant announced in September 2006); see here for an overview and Stephen Bingham's site for more details.
	EPSRC grant announced in October 2007 for a collaboration led by Professor Paul Coleman (Bath) on the development of a spin-polarised positron beam for the nanoscale study of magnetic structures.
	Leverhulme grant announced in January 2009 for a collaboration led by Professor Simon Bending on hybrid spintronic devices.

Samples have been supplied for these studies by many academic and industrial groups world-wide and the phenomena investigated include:

	the magneto-optics of dilute magnetic semiconductors;
	the study of magnetic ions in wide bandgap semiconductors;
	the optimisation of the growth and doping of epilayers;
	the behaviour of carriers confined in low-dimensional structures;
	the study of optically-detected spin resonance arising at metal centres in biological metallo-proteins.

PhD opportunities are usually available for well-qualified candidates.
