· JVASP-28371· NbTe2

NbTe2 is a layered transition metal dichalcogenide compound composed of niobium and tellurium, belonging to the class of two-dimensional (2D) materials with weak van der Waals interlayer bonding. This material is primarily investigated in research and emerging device applications rather than established industrial production, valued for its unique electronic and optical properties that differ significantly from bulk metals and conventional semiconductors.
