First-Principles Study of Electron Linewidths in Graphene
Cheol-Hwan Park, Feliciano Giustino, Catalin D. Spataru +2
We present first-principles calculations of the linewidths of low-energy quasiparticles in n-doped graphene arising from both the electron-electron and the electron-phonon interact…
Electron-Phonon Interactions in Graphene, Bilayer Graphene, and Graphite
Cheol-Hwan Park, Feliciano Giustino, Marvin L. Cohen +1
Using first-principles techniques, we calculate the renormalization of the electron Fermi velocity and the vibrational lifetimes arising from electron-phonon interactions in doped…
Band Offsets at the Si/SiO Interface from Many-Body Perturbation Theory
R. Shaltaf, G. -M. Rignanese, X. Gonze +2
We use many-body perturbation theory, the state-of-the-art method for band gap calculations, to compute the band offsets at the Si/SiO interface. We examine the adequacy of the…
Van Hove Singularity and Apparent Anisotropy in the Electron-Phonon Interaction in Graphene
Cheol-Hwan Park, Feliciano Giustino, Jessica L. McChesney +5
We show that the electron-phonon coupling strength obtained from the slopes of the electronic energy vs. wavevector dispersion relations, as often done in analyzing angle-resolved…
Velocity Renormalization and Carrier Lifetime in Graphene from Electron-Phonon Interaction
Cheol-Hwan Park, Feliciano Giustino, Marvin L. Cohen +1
We present a first-principles investigation of the phonon-induced electron self-energy in graphene. The energy dependence of the self-energy reflects the peculiar linear bandstruct…
