TaSe2 bulk (2H phase)

2H-phase TaSe2 is a 2D superconductor with critical temperature (Tc) of 0.32K, and exhibit incommensurate charge density waves (CDW) around 90K. Its metallic vs. semimetallic behavior is also under debate. Our crystals are grown by either flux zone method to achieve defect free crystals or CVT method which is known to introduce halide contaminants in the crystal. By default, we ship flux zone 2H-TaSe2 crystals with guaranteed superconducting and CDW behavior (the only commercially vdW TaSe2 crystals with guaranteed CDW and SC behavior). Our crystals are environmentally stable which means that they can be handled safely under ambient conditions without any need for chemical fume hood or inert glove box.
