Transport and percolation in a low-density high-mobility two-dimensional hole system
M. J. Manfra, E. H. Hwang, S. Das Sarma +3
We present a study of the temperature and density dependence of the resistivity of an extremely high quality two-dimensional hole system grown on the (100) surface of GaAs. For hig…
Electron-Electron Interactions in Graphene
S. Das Sarma, Ben Yu-Kuang Hu, E. H. Hwang +1
We discuss the validity (or not) of the ring-diagram approximation (i.e. RPA) in the calculation of graphene self-energy in the weak-coupling () limit, showing that RPA…
The quasiparticle spectral function in doped graphene
E. H. Hwang, S. Das Sarma
We calculate the real and imaginary electron self-energy as well as the quasiparticle spectral function in doped graphene taking into account electron-electron interaction in the l…
Scattering mechanisms and Boltzmann transport in graphene
Shaffique Adam, E. H. Hwang, S. Das Sarma
Different scattering mechanisms in graphene are explored and conductivity is calculated within the Boltzmann transport theory. We provide results for short-range scattering using t…
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…
