heterostructures, quantum wells, inversion In addition to heterojunctions combining graphene with 2D TMDs, researchers often design multistage carrier transport channels to further improve carrier separation efficiency. The graphene–TMD–graphene sandwich structures for high‐performance photodetectors have been demonstrated as a typical example. 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..
Title: Carrier Transport in Two-Dimensional Graphene Layers: Publication Type: Journal Article: Year of Publication:
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. Carrier transport in gated 2D graphene monolayers is theoretically considered in the presence of scattering by random charged impurity centers with density ni.
