Carrier transport in gated 2D graphene monolayers is considered in the presence of scattering by random charged impurity centers with density n i. Excellent quantitative agreement is obtained (for carrier density n>10 12 cm -2) with existing experimental data. The conductivity scales linearly with n/n i in the theory.

Title: Carrier Transport in Two-Dimensional Graphene Layers: Publication Type: Journal Article: Year of Publication: 2007: Authors: E. H. Hwang, S. Adam, and S. Das

186806-1-4. doi10.1103/PhysRevLett.98.186806 - References - Scientific Research Publishing. Graphene (/ ˈ ɡ r æ f iː n /) is an allotrope of carbon consisting of a single layer of atoms arranged in a two-dimensional honeycomb lattice. The name is a portmanteau of "graphite" and the suffix -ene, reflecting the fact that the graphite allotrope of carbon consists of stacked graphene layers.
