Title

Exploration of the Composition-Structure-Property Relations of Amorphous Materials with PFP: Applications to elastic properties of SiOC and SiON systems

Speaker

Dr. Hiroki Sakakima, Assistant Professor of the University of Tokyo

Abstract

Revealing the relations between the composition, structure, and resulting properties of amorphous materials is one of the major challenges where the contribution of computational material science is anticipated. However, accurately analyzing the various compositions of these disordered systems has been challenging. This is because the accuracy and computational costs of classical and ab initio molecular dynamics simulations have competing advantages and disadvantages. This long-standing challenge may be overcome by the universal neural network interatomic potentials, such as PFP. In this talk, we focus on amorphous dielectric materials, particularly carbon- or nitrogen-added amorphous silicon oxides (a-SiOC or a-SiON), both of which are necessary for advanced electronic devices. Using PFP, the relations between composition, structure, and elastic properties are examined. The structural and elastic properties of a-SiOC and a-SiON are examined in relation to changes in carbon and nitrogen content, as well as various O-rich and O-poor situations.
