(a) Structure of a hexagonal TMD monolayer. M atoms are in black and X atoms are in yellow. (b) A hexagonal TMD monolayer seen from above. 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).
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 ...
Molybdenum diselenide (MoSe 2) is an inorganic compound of molybdenum and selenium.Its structure is similar to that of MoS 2. [6] Compounds of this category are known as transition metal dichalcogenides, abbreviated TMDCs.
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]

Metal dichalcogenides have the formula ME 2, where M = a transition metal and E = S, Se, Te. [1] In terms of their electronic structures, these compounds are usually viewed as derivatives of M 4+ . They adopt stacked structures, which is relevant to their ability to undergo intercalation , e.g. by lithium , and their lubricating properties .
It is a two-dimensional (2D) group VII transition metal dichalcogenide (TMD). ReS 2 was isolated down to monolayers which is only one unit cell in thickness for the first time in 2014. [13] ReS 2 is found in nature as the mineral rheniite. [14]
In biochemistry, intercalation is the insertion of molecules between the bases of DNA. This process is used as a method for analyzing DNA and it is also the basis of certain kinds of poisoning. Clathrates are chemical substances consisting of a lattice that traps or contains molecules. Usually, clathrate compounds are polymeric and completely ...
