Title: The Investigation of the Superatomic Properties of Small Transition Metal Clusters
Speaker: James Gilmour, PhD Candidate, UoA, Department of Physics
Abstract: The superatom concept is one which has arisen out of cluster physics, providing an explanation as to why certain small metal clusters have properties reminiscent of individual atoms. These clusters possess a degenerate shell structure which is populated by the valence electrons of the constituent atoms, with the thermodynamic stability of the clusters increasing upon closure of one of these subshells.
Accounting for which electrons will contribute into superatom shells is a comparatively simple process for s and p block atoms, as all of the valence electrons can be considered to be delocalised. This is not necessarily so for transition metals, the valence structure of which is more complex and is heavily contextualised.
The motivation of this research is to investigate the properties of transition metal based clusters in order to account for the coexistence of phenomena such as magnetism, with the superatom model.
