Physical processes at the nanometer scale
Fundamental physical processes such as atomic diffusion, molecular recognition and self-organisation on solid surfaces are investigated using scanning tunnelling microscopy (STM), atomic force microscopy (AFM) and electron spectroscopic techniques.
The aim of the research is to explore the behaviour of atoms and molecules on surfaces where nanoscale features are created artificially via either atom manipulation or self-assembly, and hence to understand the property and stability of nanoscale structures. Research in this field has a particular importance in guiding the industry towards the realisation of a new generation of quantum devices with nanometre scale dimensions.
Recent and ongoing research projects include:
Physics of zero-gradient stepped surfaces
Assembly of molecular monolayers
Nanoscale fabrication based on nanosphere lithography
