產品信息

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. 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).

The 2H TaS2 crystals produced at HQ Graphene have a typical lateral size of ~0.6-0.8 cm, hexagonal shaped and have a metallic appearance.
