Description

Description Ta2Se8I topological superconductor vdW crystal is a Weyl semimetal. At temperatures below Tc = 263 K, (TaSe4)2I forms a disproportionate CDW phase, undergoing a Peierls-like phase transition. This is accompanied by a gap opening of about 260 meV.

Features And Benefits

Features And Benefits Our Ta2Se8I crystals are synthesized using self-transport technology at high temperature and pressure for extended periods of time to ensure perfect stoichiometry and chemical properties without defects. Packages are sealed at 1E-6 Torr or better, once pumped, the material may shrink due to negative pressure and its fibrous nature. This is normal and the vacuum allows us to preserve the material quality.

Application

Application Energy storage, catalysis, analytical chemistry, mechanics, adsorption, biology, microelectronics, sensors, etc.
