PtSe2 is a layered transition metal dichalcogenide (TMD) semiconductor composed of platinum and selenium in a 1:2 stoichiometry. This is primarily a research and emerging materials compound, not yet widely commercialized, valued for its tunable electronic properties and strong light-matter interactions in thin-film form. Engineers investigating PtSe2 are typically exploring it for next-generation optoelectronic devices, flexible electronics, and quantum applications where the layered crystal structure and direct bandgap characteristics offer advantages over conventional silicon and III-V semiconductors.
