TcS2

Technetium disulfide (TcS2) is a layered transition metal dichalcogenide semiconductor, a class of materials with stacked atomic planes held together by weak van der Waals forces. While primarily a research compound rather than an established industrial material, TcS2 belongs to the dichalcogenide family (alongside MoS2 and WS2) that shows promise for two-dimensional electronics, catalysis, and energy storage applications. Engineers studying this material are typically exploring its potential in next-generation devices where layer-dependent electronic properties and high surface area become advantageous—such as in flexible electronics, heterojunction devices, or catalytic applications—though commercial deployment remains limited due to technetium's radioactivity and scarcity.
