WebJul 22, 2024 · This system undergoes successive first-order phase transitions upon cooling. First, from the high-temperature incommensurate CDW state (IC state), 1T-TaS 2 enters a nearly commensurate CDW state (NC state) at 350 K. It then undergoes a phase transition to a commensurate state (C state) at 180 K, below which a Mott gap develops (22, 23). WebAug 10, 2024 · Second, the bandgap opening does not occur in all CDW phases, i.e., most of the CDW phases show metallic behavior, albeit the electrical conductivity of the CDW phases is usually lower than that of the normal uniform phase. Therefore, the design of 2-D-CDW based devices requires extensive knowledge of the CDW phases including the …

Moreover, we found that CDW … WebJan 22, 2024 · The CDW phase pattern in the time-resolved experiment is a direct consequence of the spatiotemporal nonequilibrium and strongly deviates from the situation observed under constant heating of the structure using a 532-nm continuous-wave laser (Fig. 3A and movie S3): Upon increasing the laser heating intensity, an IC domain …
Webthe resistivity in the NC phase which is determined by a continuous reduction of the Fermi surface. At the NC-C phase transition, this continuous CDW effect is convoluted by an additional effect localizing simultaneously the d conduction electrons and opening an energy gap. In the C phase the entire crystal is in a semiconducting gap state.
