Electronic transport in two dimensional Si:P -doped layers
E. H. Hwang, S. Das Sarma
We investigate theoretically 2D electronic transport in Si:P -doped layers limited by charged-dopant scattering. Since the carrier density is approximately equal to the dopant i…
Density dependent electrical conductivity in suspended graphene: Approaching the Dirac point in transport
S. Das Sarma, E. H. Hwang
We theoretically consider, comparing with the existing experimental literature, the electrical conductivity of gated monolayer graphene as a function of carrier density, temperatur…
Valley-dependent 2D transport in Si-MOSFETs
E. H. Hwang, S. Das Sarma
Motivated by interesting recent experimental results, we consider theoretically charged-impurity scattering-limited 2D electronic transport in (100), (110), and (111)-Si inversion…
Gate tunable quantum transport in double layer graphene
K. Kechedzhi, E. H. Hwang, S. Das Sarma
We analyze the effect of screening provided by the additional graphene layer in double layer graphene heterostructures (DLGs) on transport characteristics of DLG devices in the met…
Interplay between phonon and impurity scattering in 2D hole transport
Hongki Min, E. H. Hwang, S. Das Sarma
We investigate temperature dependent transport properties of two-dimensional p-GaAs systems taking into account both hole-phonon and hole-impurity scattering effects. By analyzing…
Velocity renormalization and anomalous quasiparticle dispersion in extrinsic graphene
S. Das Sarma, E. H. Hwang
Using many-body diagrammatic perturbation theory we consider carrier density- and substrate-dependent many-body renormalization of doped or gated graphene induced by Coulombic elec…
Effect of charged impurity correlation on transport in monolayer and bilayer graphene
Qiuzi Li, E. H. Hwang, E. Rossi
We study both monolayer and bilayer graphene transport properties taking into account the presence of correlations in the spatial distribution of charged impurities. In particular…
The compressibility of graphene
D. S. L. Abergel
We present a review of the electronic compressibility of monolayer and bilayer graphene. We focus on describing theoretical calculations of the effects of electron--electron intera…
2D transport and screening in topological insulator surface states
S. Adam, E. H. Hwang, S. Das Sarma
We study disorder effects on the surface states of the topological insulator BiSe close to the topologically protected crossing point. Close to charge neutrality, local flu…
