"God made solids, but surfaces were the work of the devil." -Wolfgang Pauli
Our surface group aims to understand chemical and physical processes that occur at the solid-vacuum interface and in thin-films grown on surfaces or exfoliated from bulk materials. In particular, we are interested in the interplay between the morphology and electronic structure of nano-structured surfaces. We are also interested in surface chemistry and catalysis. We study a variety of materials including exfoliated and epitaxially grown graphene, single crystal metals, both flat and decorated with nano-scale step arrays.
We employ a variety of experimental techniques such as Scanning Tunneling Microscopy (STM), Temperature Programmed Desorption (TPD), Angle Resolved PHotoemission Spectroscopy (ARPES) and Low Energy Electron Diffraction (LEED).
