Strain-Induced Curvature in Monolayer Graphene: Effects on Electronic Structure, Phonon Dynamics, and Lattice Thermal Conductivity
M. C. Santos, E. Lora da Silva, D. S. Baptista +6
We present a comprehensive set of calculations to investigate the effect of strain-induced x-y topological perturbation in the monolayer graphene sheet. We show that the induced cu…
Theoretical study of the stability of the tetradymite-like phases of SbS, BiS, and SbSe
E. Lora da Silva, J. M. Skelton, P. Rodríguez-Hernández +5
We report a comparative theoretical study of the \textit{Pnma} and \textit{R-3m} phases of SbS, BiS, and SbSe close to ambient pressure. Our enthalpy calcul…
-AsTe: Pressure-Induced 3D Dirac Semi-Metal
E. Lora da Silva, A. Leonardo, Tao Yang +5
We report a theoretical \textit{ab-initio} study of -AsTe ( symmetry) at hydrostatic pressures up to 12 GPa. We have systematically characterized the vibratio…
Electronic and Phonon Instabilities in Bilayer Graphene under Applied External Bias
E. Lora da Silva, M. C. Santos, J. M. Skelton +4
We have performed electronic-structure and lattice-dynamics calculations on the AB and AA structures of bilayer graphene. We study the effect of external electric fields and compar…
Electric bias control on impurity effects in bigraphene
Y. G. Pogorelov, M. C. Santos, V. M. Loktev
Formation of localized impurity levels within the band gap in bigraphene under applied electric field is considered and the conditions for their collectivization at finite impurity…
Optical conductivity of curved graphene
A. J. Chaves, T. Frederico, O. Oliveira +2
We compute the optical conductivity for an out-of-plane deformation in graphene using an approach based on solutions of the Dirac equation in curved space. Different examples of pe…
