Our research is focussed upon the application of first-principles theory and ultra-high-vacuum single-crystal experiments to problems in surface chemistry and catalysis. We make use of fibre-optic low-energy electron diffraction (FO-LEED) to obtain structural information, reflection absorption infra-red spectroscopy (RAIRS) to obtain vibrational information, single-crystal adsorption calorimetry (SCAC) to obtain energetic information, supersonic molecular beams (SMB) to obtain kinetic information, and low- temperature scanning tunnelling microscopy (LT-STM) to obtain morphological, topographic and electronic information about surfaces and the molecules that adsorb, diffuse and react upon them. Density functional theory (DFT) provides a framework within which to calculate comparable data, which aids in the interpretation of our experimental work.

Our work is concentrated within four main research themes:

  • complex interadsorbate interactions; 
  • nanoscale surface phenomena; 
  • chiral surface systems;
  • and tuning reactivity and catalysis.

Individual research projects are chosen to reflect these themes, lending coherence to a diverse range of topical studies. Thus, by way of example, our work on the adsorption of alanine on Cu{531} addresses issues relating to the formation of complex hydrogen-bonded adsorbate networks, whilst also shedding light on the interaction of chiral molecules with an intrinsically chiral metal surface; moreover, certain adsorbates can cause this unstable surface to break up into nanoscale facets, whose catalytic properties will differ markedly from those of the notionally ideal surface. Tackling these interlinked aspects of surface science requires a flexible approach, making use of multiple experimental techniques complemented by a rigorously benchmarked theoretical methodology.
