“…[110] The optical properties of the 2D MoS 2 material are sensitive to the number of layers and interlayer distance, which makes it diffi cult to anticipate the optical properties of these materials. [111,112] Su et al [113] examined the optical conductivity of the a hetero structure consisting of MoS 2 and arsenene. They found varia tion in the conductivity of the heterostructure which was as a result of the variation in the interlayer distance.…”

“…Among van der Waals layered materials, transition metal dichalcogenides (TMDs) have recently gained attention from the scientific community for their peculiar optoelectronic characteristics [1][2][3][4][5]. Indeed, TMDs exhibit a unique combination of atomic-scale thickness, direct bandgap, strong spin-orbit coupling and favorable electronic and mechanical properties [6][7][8][9], which make them interesting for fundamental studies as well as for applications in energy harvesting [10,11], optoelectronics [12][13][14][15][16][17], spintronics [18], data storage [19,20], synaptic devices [21,22], flexible devices [23][24][25][26][27], etcetera.…”

Mechanically exfoliated multilayer WS2 flakes are used as the channel of field effect transistors for low-power photodetection in the visible and near-infrared (NIR) spectral range. The electrical characterization as a function of the temperature reveals devices with n-type conduction and slightly different Schottky barriers at the drain and source contacts. The WS2 phototransistors can be operated in self-powered mode, yielding both a current and a voltage when exposed to light. The spectral photoresponse in the visible and the NIR ranges shows a high responsivity (4.5 μA/W) around 1250 nm, making the devices promising for telecommunication applications.

“…[12] Among layered materials, transition metal dichalcogenides (TMDs) have been the subject of much research lately due to their interesting optical, electrical, chemical, and thermal properties. [14][15][16][17][18][19] Helveg et al [20] used scanning tunneling microscopy to obtain real-space images of MoS 2 nanoclusters, showing two different kinds of termination: sulfur-terminated ( � 1010) edges and molybdenum-terminated (10 � 10) edges. These edges present different chemical activity, [21] and therefore offer possible catalytical selectivity.…”

Transition-metal dichalcogenides (TMDs) have promising properties for their use as catalysts of CO 2 reduction to methane via the Sabatier reaction. In this article we use density-functional theory calculations to gain insight into the energetics of this reaction for Mo/W-based and S/Se-based TMDs with non-, Niand Cu-doping. We show that sulfur-based TMDs with Ni/Cu doping exhibit better indicators for catalytic performance of the CO 2 reduction reaction than non-doped and doped TMDs without active sites. In addition, the role of the transition metal was found to a much smaller influence in the reaction than the role of the chalcogen and dopant atoms, which influence the bonding strength and type, respectively.
