Rani | Extern (zero) gap for the other and thus are useful for tunable spin transport applications. and (iii) the availability of both charge carriers, i.e., electrons as well as holes, Later, several other systems, including 2-​dimensional materials, were chern insulator, atomic layers, band-gap, metal, graphene, Physics.

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.. Each atom in a graphene sheet is connected to its three nearest neighbors by a σ-bond, and CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): A broad review of fundamental electronic properties of two-dimensional graphene with the emphasis on density and temperature-dependent carrier transport in doped or gated graphene structures is provided.
