Modeling electromigration using the peridynamics approach

David T. Read, Walter Gerstle, Vinod K. Tewary
This chapter presents a summary of the information and reasoning needed to justify learning about peridynamics for the purpose of analyzing electromigration and

Graphene-metal interconnect: an atomistic simulation

Alexander Y. Smolyanitsky, Vinod K. Tewary
We develop a set of computationally efficient and accurate interatomic interactions for an atomistic simulation of the properties of graphene on nickel surface

Simulation of lattice strain due to CNT-metal interface

Alexander Y. Smolyanitsky, Vinod K. Tewary
We report an atomistic molecular statics study of strains in single wall carbon nanotubes (SWCNTs) interfaced with a planar nickel surface. We calculate axial

Singularity in the Debye-Waller factor of graphene

Vinod K. Tewary, B. Yang
It is shown that the Debye-Waller factor for graphene has a singularity. However, the singularity does not affect the zero-temperature value of the Debye-Waller

A parametric interatomic potential for graphene

Vinod K. Tewary, B. Yang
A parametric interatomic potential is constructed for graphene. The potential energy consists of two parts: bond energy and radial interaction energy. The bond

Peridynamic Simulation of Electromigration

David T. Read, Walter Gerstle, Stewart Silling, Vinod K. Tewary, Richard Lehoucq
A theoretical framework, based upon the peridynamic model, is presented for analytical and computational simulation of electromigration. The framework allows

Multiscale Model of Germanium Quantum Dots in Silicon

David T. Read, Vinod K. Tewary
Atomic displacements, strains and strain energies in the neighborhood of near-spherical, coherent germanium ¿quantum dots¿ (QD) in crystalline silicon and near
