Transition Metal Chalcogenides (TMCs)


Transition Metal Chalcogenides
Transition Metal Chalcogenides

Transition metal chalcogenides (TMCs) are compounds composed of a transition metal (Mo, W, Zr, etc.) and a chalcogen element (O, S, Se, etc.). They have the general formula MXy where M is the transition metal, X is the chalcogen element and y represents the number of atmons per metal. These materials exhibit diverse electronic properties ranging from metallic to semiconducting, which makes them important for various applications in electronics, catalysis, and energy storage.

2D TMCs consist of layers that vary based on the specific transition metal and chalcogen involved. The versatility in their bonding and structure leads to a variety of desirable properties and functionalities. These include suitable and modifiable band gaps, which are ideal for electronic and optoelectronic applications.

Some of the most studied TMCs are transition metal dichalcogenides (TMDs or TMDCs), such as molybdenum disulfide (MoS2) and tungsten disulfide (WS2). They are noted for their promising potential in next-generation electronic and optoelectronic devices.
