Transition-metal dichalcogenide (TMD or TMDC) monolayers are atomically thin semiconductors of the type MX 2, with M a transition-metal atom (Mo, W, etc.) and X a chalcogen atom (S, Se, or Te). One layer of M atoms is sandwiched between two layers of X atoms.
Transition-metal dichalcogenide monolayers (TMDs or TMDCs) are a class of two-dimensional materials that have the chemical formula MX 2, where M represents transition metals from group IV, V and VI, and X represents a chalcogen such as sulfur, selenium or tellurium. [6] MoS 2, MoSe 2, MoTe 2, WS 2 and WSe 2 are TMDCs. TMDCs have layered ...
NbSe 2 crystallizes in several related forms, and can be mechanically exfoliated into monatomic layers, similar to other transition metal dichalcogenide monolayers. Monolayer NbSe 2 exhibits very different properties from the bulk material, such as of Ising superconductivity, quantum metallic state, and strong enhancement of the CDW. [3]
MoS 2, the most common metal dichalcogenide, adopts a layered structure. Metal dichalcogenides have the formula ME 2, where M = a transition metal and E = S, Se, Te. [7] The most important members are the sulfides. They are always dark diamagnetic solids, insoluble in all solvents, and exhibit semiconducting properties. Some are superconductors ...
Platinum diselenide is a transition metal dichalcogenide with the formula PtSe 2. It is a layered substance that can be split into layers down to three atoms thick. PtSe 2 can behave as a metalloid or as a semiconductor depending on the thickness.
