Name: Niobium Disulfide (2H NbS2)
SKU: ACM12136979-4
Rating: 5 (1 reviews)

Description

Description Niobium disulfide (NbS2) is a two-dimensional metal (3R phase) and two-dimensional superconductor (2H phase), depending on the crystalline phase. NbS2 (2H phase) is a superconductor with Tc ~6K and charge density wave (CDW) system. The layers are stacked together via van der Waals interactions and can be exfoliated into thin 2D layers. NbS2 belongs to the group V transition metal dichalcogenides (TMDC).

Features And Benefits

Features And Benefits The 2H NbS2 crystals we produce have typical lateral dimensions of about 0.2 cm, are triangular/hexagonal and have a metallic appearance.

Application

Application New 2D semiconductors, topological insulators, and superconductors have numerous applications in advanced technologies, and Alfa Chemistry engineers can guide customers in material characterization and selection.
