Mechanisms of plastic deformation in amorphous silicon by atomistic simulation using the Stillinger-Weber potential
… simulation of amorphous silicon (a-Si) using the Stillinger- Weber potential reveals the existence of two distinct atomic environments: one solidlike and the other liquidlike. The mechanical behavior of a-Si when plastically deformed to large strain can be completely described by the mass fraction …

Phenomenology and kinematics of discrete plastic deformation events in amorphous silicon : atomistic simulation using the Stillinger-Weber potential
The need to understand plastic deformation in amorphous covalently bonded materials arose from the unique mechanical properties of disordered intergranular layers in nc-TiN/a-Si₃N₄ ceramic composites. Silicon was chosen as a model disordered network solid for the purpose of conducting feasible …

Methods for Accurately Modeling Complex Materials
We investigate and benchmark a variety of computational methods for accurately modeling complex materials. We focus on three specific methods used to examine systems with real world interest: screened hybrid density functional theory (DFT) used for accurate treatment of band gaps in semiconductors, …
