Transition Metal Dichalcogenides (TMDs) are a class of materials with the general formula MX2, where M is a transition metal (such as Mo, W, or Ti) and X is a chalcogen (such as S, Se, or Te). These materials form layered structures with unique electronic, optical, and catalytic properties. Their structure consists of a transition metal layer sandwiched between two chalcogen layers, creating a two-dimensional (2D) material.
