2H-phase niobium diselenide 2H-NbSe2) is a superconducting vdW crystal with charge density wave (CDW) and Weyl semimetal properties. It has a superconducting critical temperature of ~7.8K and charge density wave behavior at ~34K. Owing to extremely low point defect density well below (1E10 cm-2), our NbSe2 crystals are the only commercially available crystals with guaranteed superconducting and CDW behavior. Similar to molybdenum disulfide, it has layered structure (lamellar) with weak interlayer coupling. NbSe2 displays metallic and superconducting behavior. Undergoes superconducting transition at low temperatures, exhibits CDW behavior. Unlike other sources, our NbSe2 crystals are grown by defect and impurity free flux zone technique (see the comparison between chemical vapor transport [CVT] below). Clean and defect free nature enabled researchers to observe clean superconductivity, phase transitions, and perform quantum transport measurements with confidence in the crystal. If your research needs atomically flat NbSe2 samples for scanning tunneling microscopy (STM) measurements please contact us.
