· Nb2 Se4

Niobium diselenide (Nb₂Se₄) is a layered transition metal chalcogenide semiconductor belonging to the family of two-dimensional materials with anisotropic crystal structure. This compound is primarily investigated in materials research for next-generation electronics and energy applications, where its semiconducting properties and layer-dependent behavior make it attractive as an alternative to commercially established materials like MoS₂ for field-effect transistors, photodetectors, and catalytic devices.
