Comparison of dislocation density tensor fields derived from discrete dislocation dynamics and crystal plasticity simulations of torsion
Reese Jones, Jonathan Zimmerman, Giacomo Po
The importance of accurate simulation of the plastic deformation of ductile metals to the design of structures and components is well-known. Many techniques exist that address the…
Atomistic Potentials for Palladium-Silver Hydrides
L. M. Hale, B. M. Wong, J. A. Zimmerman +1
New EAM potentials for the ternary palladium-silver-hydrogen system are developed by extending a previously developed palladium-hydrogen potential. The ternary potentials accuratel…
Energetics and diffusion of gold in bismuth telluride
Michael C. Shaughnessy, Josh D. Sugar, Norm C. Bartelt +1
We have coupled electron microscopy and energy dispersive spectroscopy experiments with \textit{ab-initio} modeling to study the solubility and diffusion of Au in BiTe. We…
Molecular Dynamics Studies of Dislocations in CdTe Crystals from a New Bond Order Potential
X. W. Zhou, D. K. Ward, B. M. Wong +2
Cd1-xZnxTe (CZT) crystals are the leading semiconductors for radiation detection, but their application is limited by the high cost of detector-grade materials. High crystal costs…
High-fidelity simulations of CdTe vapor deposition from a new bond-order potential-based molecular dynamics method
X. W. Zhou, D. Ward, B. M. Wong +8
CdTe has been a special semiconductor for constructing the lowest-cost solar cells and the CdTe-based Cd1-xZnxTe alloy has been the leading semiconductor for radiation detection ap…
Modeling metallic island coalescence stress via adhesive contact between surfaces
Steven C. Seel, Jeffrey J. Hoyt, Edmund B. Webb +1
Tensile stress generation associated with island coalescence is almost universally observed in thin films that grow via the Volmer-Weber mode. The commonly accepted mechanism for t…
Dislocation Emission around Nanoindentations on a (001) fcc Metal Surface Studied by STM and Atomistic Simulations
O. Rodriguez de la Fuente, J. A. Zimmerman, M. A. Gonzalez +4
We present a combined study by Scanning Tunneling Microscopy and atomistic simulations of the emission of dissociated dislocation loops by nanoindentation on a (001) fcc surface. T…
