VSe2 (1T Vanadium Diselenide)

1T VSe2 Vanadium Diselenide 1T-VSe2 is a metal and a Charge density waves (CDW) system, having the incommensurate CDW state below 110K. The layers are stacked together via van der Waals interactions and can be exfoliated into thin 2D layers. 1T VSe2 belongs to the group-V transition metal dichalcogenides (TMDC).
