16 Aug 2017 Besides graphene, transition metal dichalcogenides (TMDCs) and layered It is well known that most 2D layered materials exist in a bulk state. which makes it possible to tune the carriers transport in an electronic
Charge carriers in graphene show linear, rather than quadratic, dependence of energy on Charge transport is The advancement of novel layered two-dimensional (2D) materials, including graphene41,42,55–65, transition metal dichalcogenide (TMD) layers66, and black JD Sau, RM Lutchyn, S Tewari, SD Sarma. Physical review letters 104 (4), 040502, 2010. 1743, 2010. Carrier transport in two-dimensional graphene layers.
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..

In this Letter, we map for the first time the current distribution among the individual layers of multilayer two-dimensional systems. Our findings suggest that in a multilayer MoS2 field-effect transistor the “HOT-SPOT” of the current flow migrates dynamically between the layers as a function of the applied back gate bias and manifests itself in a rather unusual “contact resistance
We provide a broad review of fundamental electronic properties of two-dimensional graphene with the emphasis on density and temperature dependent carrier
Electrical conductivity along the basal plane of TGCN is 65 times lower than through the stacked layers, as opposed to graphite. Furthermore, we develop a model for this charge‐transport behavior based on observed carrier dynamics and random‐walk simulations.
