Abstract Scope |
Amorphous oxides are important functional materials for a number of next generation electronics applications, both because of their ability to accept and immobilize electrons in multilayer devices, and because of the tunability of the amorphous atomic packing. In this talk, we present our multiscale statistical study of the relationships between properties and local and intermediate range structure in amorphous alumina (a-Al2O3,). For this, we link classical molecular dynamics simulations with small-scale high fidelity density functional theory calculations of electronic structure to generate a representative ensemble of structural models, and use metrics of local disorder, packing and metrics of the intermediate range bonding graph to identify local structural motifs responsible for frontier electronic states. |
