Assessment of Vacancy Formation and Surface Energies of Materials using Classical Force-Fields

September 07, 2018

Author(s):

Kamal Choudhary, Adam J. Biacchi, Supriyo Ghosh, Lucas M. Hale, Angela R. Hight Walker, Francesca M. Tavazza

In this work, we present an open access database for surface and vacancy-formation energies using classical force-fields (FFs). These quantities are essential...

Probing the dielectric response of the interfacial buffer layer in epitaxial graphene via optical spectroscopy

November 28, 2017

Author(s):

Heather M. Hill, Albert F. Rigosi, Sugata Chowdhury, Yanfei Yang, Nhan V. Nguyen, Francesca M. Tavazza, Randolph E. Elmquist, David B. Newell, Angela R. Hight Walker

Monolayer epitaxial graphene (EG) is a suitable candidate for a variety of electronic applications. One advantage of EG growth on the Si face of SiC is that it...

Evaluation and comparison of classical interatomic potentials through a user-friendly interactive web-interface

Author(s):

Kamal Choudhary, Faical Y. Congo, Chandler A. Becker, Francesca M. Tavazza

Classical empirical potentials/force-fields (FF) provide atomistic insights into material phenomena through molecular dynamics and Monte Carlo simulations...

Identification of the Crystal Symmetry in 1T′ MoTe2 with Polarization-Resolved Second Harmonic Generation and Raman Scattering

October 13, 2016

Author(s):

Ryan Beams, Luiz Gustavo Cancado, Sergiy Krylyuk, Irina Kalish, Berc Kalanyan, Arunima Singh, Kamal Choudhary, Patrick Vora, Francesca M. Tavazza, Albert Davydov, Stephan J. Stranick

We study the crystal symmetry properties of few-layer 1T' MoTe2 using the polarization dependence of the second harmonic generation (SHG) and Raman scattering...
