Inversion of diffraction data for amorphous materials

A Pandey, P Biswas, DA Drabold - Scientific Reports, 2016 - nature.com
The general and practical inversion of diffraction data–producing a computer model correctly
representing the material explored–is an important unsolved problem for disordered …

Force-enhanced atomic refinement: Structural modeling with interatomic forces in a reverse Monte Carlo approach applied to amorphous Si and

A Pandey, P Biswas, DA Drabold - Physical Review B, 2015 - APS
We introduce a structural modeling technique, called force-enhanced atomic refinement
(FEAR). The technique incorporates interatomic forces in reverse Monte Carlo (RMC) …

Experimentally constrained molecular relaxation: The case of glassy

P Biswas, DN Tafen, DA Drabold - Physical Review B—Condensed Matter and …, 2005 - APS
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 …

Models and modeling schemes for binary IV-VI glasses

DN Tafen, DA Drabold - Physical Review B—Condensed Matter and Materials …, 2005 - APS
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 …

Realistic inversion of diffraction data for an amorphous solid: The case of amorphous silicon

A Pandey, P Biswas, B Bhattarai, DA Drabold - Physical Review B, 2016 - APS
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 …

Silver transport in materials: Ab initio simulation of a solid electrolyte

DN Tafen, DA Drabold, M Mitkova - Physical Review B—Condensed Matter …, 2005 - APS
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 …
