My research focuses on three different themes:
- The extreme properties of diamond mean that it could surpass other wide band gap materials in many optical and electronic applications. Ultimately, the electrical and optical properties will be limited by defects and impurities either grown-in, introduced during processing steps involved in modern device fabrication, or produced via possible degradation processes during device operation. This motivates work on understanding and determining the electronic properties and lattice structures of defects, as well as the diffusion of impurities and activation of dopants in diamond. The group uses a wide range of spectroscopic and microscopic techniques to study, engineer and exploit defects in diamond. See go.warwick.ac.uk/diamond.
- The development of new technologies, techniques and methodologies for Electron Paramagnetic Resonance (EPR), Dynamic Nuclear Polarisation (DNP) and optical spectroscopies. Advances in instrumentation provide the competitive edge and underly almost everything that goes on in experimental science. See go.warwick.ac.uk/DNP.
- Boron doped diamond (BDD) is presently the subject of considerable interest as an electrode material. This is a consequence of its very wide potential window in aqueous solution, low background currents, and corrosion stability in aggressive media. In collaboration with the Warwick Electrochemistry and Interfaces Group, we are investigating the electrical and electrochemical properties of single crystal and polycrystalline BDD and developing diamond based sensor technologies. See www.warwick.ac.uk/electrochemistry.
I am also Director of the Centre for Doctoral Training (CDT) in Integrated Magnetic Resonance (iMR) which involves internationally-leading researchers at the Universities of Warwick, St Andrews/Dundee, Southampton, Nottingham and Aberdeen as well as all the major industrial magnetic resonance companies.
