NbS2 (2H Niobium Disulfide)
NbS2 (2H phase) is a metal, a superconductor with a Tc ~6K and a charge density waves (CDW) system. Note that NbS2 also exists in the 3R-NbS2 phase (for the 3R phase NbS2 click here) 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).
