2H-TaS2 is a metal and an incommensurate Charge density waves (CDW) system below ~75-80K and a superconductor with Tc ~1K. Note that TaS2 also exist in the 1T phase TaS2 which is a semiconductor and a Charge density waves (CDW) system below ~180K (for more information on 1T-TaS2 click here). The layers are stacked together via van der Waals interactions and can be exfoliated into thin 2D layers. TaS2 belongs to the group-V transition metal dichalcogenides (TMDC).
