My main research interest is in the properties of nanometre scale particles (called 'atomic clusters') and in developing ways of building nano-electronic devices from these clusters. My group are currently working on cluster-based devices with applications ranging from chemical sensors to magnetic field sensors to transistors. We also have a unique apparatus for studying unusual atomic arrangements within these particles, including 5-fold symmetric structures forbidden in ordinary crystals.
