Electron supercollimation in graphene and Dirac fermion materials using one-dimensional disorder potentials
SangKook Choi, Cheol-Hwan Park, Steven G. Louie
Electron supercollimation, in which a wavepacket is guided to move undistorted along a selected direction, is a highly desirable property that has yet been realized experimentally.…

Quasiparticle Energies and Band Gaps of Graphene Nanoribbons
Li Yang, Cheol-Hwan Park, Young-Woo Son +2
We present calculations of the quasiparticle energies and band gaps of graphene nanoribbons (GNRs) carried out using a first-principles many-electron Green's function approach with…
