Two-dimensional electronic transport on the surface of 3D topological insulators
Qiuzi Li, E. Rossi, S. Das Sarma
We present a theoretical approach to describe the 2D transport properties of the surfaces of three dimensional topological insulators (3DTIs) including disorder and phonon scatteri…
Screening and collective modes in gapped bilayer graphene
C. Triola, E. Rossi
We study the static and dynamic screening of gapped bilayer graphene. Unlike previous works we use the 4-band model instead of the simplified 2-band model. We find that there are i…
Inhomogeneity and nonlinear screening in gapped bilayer graphene
D. S. L. Abergel, E. Rossi, S. Das Sarma
We demonstrate that for gapped bilayer graphene, the nonlinear nature of the screening of an external disorder potential and the resulting inhomogeneity of the electron liquid are…
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…
