Description

Description Ta2NiTe5 is one of the newest members of vdW crystals. It is located in the intersection region between the Weyl metal and the exciton insulator.

Features And Benefits

Features And Benefits Excitonic insulators are novel material systems that exhibit correlated electronic phases. When the exciton binding energy (Eb) is greater than the band gap (Eg), the excitons condense to their ground state. Exciton condensation in semiconductors occurs via the Bose-Einstein condensation process, whereas condensation in semimetals occurs via the Bardeen-Cooper-Schrieffer (BCS) process. Spontaneous band hybridization induced by Coulomb attraction between orthogonal conduction (electron) and valence (hole) bands opens the band gap and drives the system into an insulating state

Application

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