Rev. Lett. 98, 186806 (2007). Article Google Scholar 24. 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.

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. We explain the experimentally observed asymmetry between electron and
