NbSe2 (2H Niobium Diselenide)
2H-NbSe2 is superconductor with Tc ~7.2K and a Charge Density Waves (CDW) system with Tcdw of ~33K. The layers are stacked together via van der Waals interactions and can be exfoliated into thin 2D layers. 2H NbSe2 belongs to the group-V transition metal dichalcogenides (TMDC).
