Electron-Phonon Coupling in Two-Dimensional Silicene and Germanene
Jia-An Yan, Ryan Stein, David M. Schaefer +2
Following the work in graphene, we report a first-principles study of electron-phonon coupling (EPC) in low-buckled (LB) monolayer silicene and germanene. Despite of the similar ho…
Phonon dispersions and vibrational properties of monolayer, bilayer, and trilayer graphene
Jia-An Yan, W. Y. Ruan, M. Y. Chou
The phonon dispersions of monolayer and few-layer graphene (AB bilayer, ABA and ABC trilayers) are investigated using the density-functional perturbation theory (DFPT). Compared wi…
Electron-Phonon Interactions for Optical Phonon Modes in Few-Layer Graphene
Jia-An Yan, W. Y. Ruan, M. Y. Chou
We present a first-principles study of the electron-phonon (e-ph) interactions and their contributions to the linewidths for the optical phonon modes at and K in one to three-l…
Comparative study of density functional theories of the exchange-correlation hole and energy in silicon
A. C. Cancio, M. Y. Chou, Randolph Q. Hood
We present a detailed study of the exchange-correlation hole and exchange-correlation energy per particle in the Si crystal as calculated by the Variational Monte Carlo method and…
Theoretical study of hydrogen-covered diamond (100) surfaces: A chemical potential analysis
Suklyun Hong, M. Y. Chou
The bare and hydrogen-covered diamond (100) surfaces were investigated through pseudopotential density-functional calculations within the local-density approximation. Different cov…
