Theory of charged impurity scattering in two dimensional graphene
S. Adam, E. H. Hwang, E. Rossi +1
We review the physics of charged impurities in the vicinity of graphene. The long-range nature of Coulomb impurities affects both the nature of the ground state density profile as…
Graphene magnetoresistance in a parallel magnetic field: Spin polarization effect
E. H. Hwang, S. Das Sarma
We develop a theory for graphene magnetotransport in the presence of carrier spin polarization as induced, for example, by the application of an in-plane magnetic field () paral…
The Observation of Percolation-Induced 2D Metal-Insulator Transition in a Si MOSFET
L. A. Tracy, E. H. Hwang, K. Eng +6
By analyzing the temperature () and density () dependence of the measured conductivity () of 2D electrons in the low density (cm) and temperature (0.02…
Ballistic Hot Electron Transport in Graphene
Wang-Kong Tse, E. H. Hwang, S. Das Sarma
We theoretically study the inelastic scattering rate and the carrier mean free path for energetic hot electrons in graphene, including both electron-electron and electron-phonon in…
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…
Limit to 2D mobility in modulation-doped GaAs quantum structures: How to achieve a mobility of 100 millions
E. H. Hwang, S. Das Sarma
Considering scattering by unintentional background charged impurities and by charged dopants in the modulation doping layer as well as by GaAs acoustic phonons, we theoretically co…
