Thierry Maffeis obtained his Ph.D. degree from the University of Sheffield Hallam, South Yorkshire, UK, in 2000 and then joined Swansea University as a Postdoctoral Research Assistant. He is currently a Lecturer at the Multidisciplinary Nanotechnology Centre in the College of Engineering. His background is in the field of surface science, specifically applied to a wide range of semiconductors including established materials (Si, GaAs), wide band-gap (GaN, SiC), and polycrystalline nanoscale metal-oxide (SnO2, Fe2O3, ZnO, and WO3). His current research is centred on the fabrication and characterisation of ZnO nanostructures and their surface properties using a variety of techniques including field emission SEM, X-ray photoelectron spectroscopy, scanning probe microscopy, and photoluminescence. Maffeis is particularly interested in the effect of surface chemistry on the electrical and optical properties of ZnO nanostructures and how it can be controlled to improve gas sensing devices. He also investigates the basic interaction of ZnO nanowire arrays with cells in collaboration with a view to developing biosensors and nanoengineered substrates. He has published more than 35 peer-reviewed papers.
