(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 ...

It is a water-insoluble, gray-black solid. VTe2 has no applications but closely related layered dichalcogenides are subject of much research. [1] VTe 2 is the best studied vanadium telluride. Vanadium ditelluride can be prepared by the reaction of the elements at 1000 °C. [2] The reaction can also be conducted in molten salt. [3]
Siegenite (also called grimmite, or nickel cobalt sulfide) is a ternary transition metal dichalcogenide compound with the chemical formula (Ni,Co) 3 S 4.It has been actively studied as a promising material system for electrodes in electrochemical energy applications due to its better conductivity, greater mechanical and thermal stability, and higher performance compared to metal oxides ...
Compounds of this category are known as transition metal dichalcogenides, abbreviated TMDCs. These compounds, as the name suggests, are made up of a transition metals and elements of group 16 on the periodic table of the elements. Compared to MoS 2, MoSe 2 exhibits higher electrical conductivity. [7]
Niobium diselenide or niobium(IV) selenide is a layered transition metal dichalcogenide with formula NbSe 2.Niobium diselenide is a lubricant, and a superconductor at temperatures below 7.2 K that exhibit a charge density wave (CDW).
