In this Colloquium, I describe some current frontiers in the physics of semiconducting amorphous materials and glasses, including a short, but self-contained discussion of …
The general and practical inversion of diffraction data–producing a computer model correctly representing the material explored–is an important unsolved problem for disordered …
We introduce a structural modeling technique, called force-enhanced atomic refinement (FEAR). The technique incorporates interatomic forces in reverse Monte Carlo (RMC) …

An ideal atomistic model of a disordered material should contradict no experiments, and should also be consistent with accurate force fields (either ab initio or empirical). We make …

In this paper, we present and thoroughly characterize several new models of amorphous binary IV-VI glasses. We apply both a quench from the melt simulation regime and a scheme …
We apply a method called “force-enhanced atomic refinement”(FEAR) to create a computer model of amorphous silicon (a-Si) based upon the highly precise x-ray diffraction …

In this paper, we present models of Ge-Se glasses heavily doped with Ag obtained from ab initio simulation and study the dynamics of the network with an emphasis on the motion of …

It is widely accepted in the materials modeling community that defect-free realistic networks of amorphous silicon cannot be prepared by quenching from a molten state of silicon using …
Density functional/molecular dynamics simulations have been performed to determine structural and other properties of amorphous Ag/Ge/S and Ge/S alloys. In the former, the …
