Density of states of disordered graphene
Ben Yu-Kuang Hu, E. H. Hwang, S. Das Sarma
We calculate the average single particle density of states in graphene with disorder due to impurity potentials. For unscreened short-ranged impurities, we use the non-self-consist…
Many-body exchange-correlation effects in graphene
E. H. Hwang, Ben Yu-Kuang Hu, S. Das Sarma
We calculate, within the leading-order dynamical-screening approximation, the electron self-energy and spectral function at zero temperature for extrinsic (or gated/doped) graphene…
Density dependent exchange contribution to in extrinsic graphene
E. H. Hwang, Ben Yu-Kuang Hu, S. Das Sarma
We calculate in extrinsic graphene as a function of carrier density at zero temperature by obtaining the electronic self-energy within the Hartree-Fock a…
Inelastic carrier lifetime in graphene
E. H. Hwang, Ben Yu-Kuang Hu, S. Das Sarma
We consider hot carrier inelastic scattering due to electron--electron interactions in graphene, as functions of carrier energy and density. We calculate the imaginary part of the…
