Research Expertise

Georg's research interests focus on fundamental aspects of heterogeneous catalysis and the development of methods for accurate characterization of adsorbed molecules. One key activity of the research group is the precise determination of surface geometries by diffraction techniques (LEED, SXRD).


Another, increasingly important field of research involves studies of the chemical nature of model catalysts and adsorbed molecules by X-ray photoelectron spectroscopy (XPS) and Near Edge X-ray Absorption Fine Structure (NEXAFS) Spectroscopy. The experiments investigate the adsorption and reactions of small bio-relevant molecules (e.g. amino acids) and solvents, like water, on metal and oxide surfaces and the geometries and electronic structures of surfaces alloys and thin oxide films.

Prof Held has been awarded major grants from EPSRC and the European Commission (network grants "MONET" and "SMALL" funded by the Marie Curie programme) and regular beamtime awards at UK, European and US synchrotron facilities.

Georg is also involved in the development and maintence of the CLEED program package for LEED-IV studies.

Biography

Georg Held received a Ph.D. in physics from the Technical University of Munich, Germany, in 1994. He was a postdoctoral research assistant at the University of Cambridge, UK (1994–1995) and staff scientist at the Universities of Würzburg and Erlangen, Germany (1995–2001). From 2001 to 2006 he was a lecturer in Physical Chemistry at the University of Cambridge, UK. Afterwards, he has been a reader in Surface Science at the University of Reading, UK and, since 2012, Georg is also part-seconded to Diamond Light Source to lead the VERSOX (VERsatile SOft X-ray) project. His research concentrates on studying structures and reactivities of bio-related surfaces.
