NbTe2 (Niobium Ditelluride)

NbTe2 Niobium Ditelluride NbTe2 is a metal and a superconductor with Tc ~0.7K. The layers are stacked together via van der Waals interactions and can be exfoliated into thin 2D layers. Niobium Ditelluride belongs to the group-V transition metal dichalcogenides (TMDC). To buy NbTe2 crystals please click here.
