Summary on Grant Application Form |
It is proposed to use ab initio molecular dynamics simulation to study the behaviour of the As-Se glass system. Structural aspects of interest include the degree of molecule formation in the glass structure. The electronic structure of the glasses will be calculated with the aim of studying localized states. The vibrational behaviour of the glasses will be investigated with regard to molecular-like features in the density of states and localization of vibrational states at band edges. The main aim, however is to study optical excitation in such glasses and the concomitant structural (and electronic) metastability introduced by such excitation with a view to obtaining a microscopic understanding of photostructural effects.
