TaS2 demonstrates a unique metal-to-insulator transition in its 1T phase with over an order of magnitude change in resistivity1. ... These effects will be correlated through our findings via AFM and Raman spectroscopy. Conclusion: 1T TaS2 demonstrates great potential as a replacement ...
WebNov 27, 2024 · Here, using the Raman spectroscopy, the electric-field-driven phase transition is in situ observed in the ultrathin 1T-TaS 2. By quantitative evaluation of the Joule heating effect in the electric-field-induced CDW transition, it is shown that Joule heating plays a secondary role in the nearly commensurate (NC) to incommensurate (IC) CDW ... WebJan 1, 2024 · The evolution of electron correlation and charge density wave (CDW) in 1T-TaS 2 single crystal has been investigated by temperature-dependent Raman scattering, which undergoes two obvious peaks of A 1g modes about 70.8 cm −1 and 78.7 cm −1 at 80 K, respectively. The former peak at 70.8 cm −1 is accordant with the lower Hubbard …
