產(chǎn)品信息

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). 
The NbTe2 crystals produced at HQ Graphene have a typical lateral size of ~0.6-0.8 cm, plate shaped and have a metallic appearance. More information on the NbTe2 crystals we sell can be found below.
