WebMay 15, 1990 · The surface atomic structure and the charge-density-wave (CDW) structure in the 1T phase of TaSe 2, TaS 2, and VSe 2 have been studied at 4.2, 77, and 300 K. The response of the scanning tunneling microscope (STM) to the CDW superlattice in 1T-TaSe 2 and 1T-TaS 2 is extremely strong, while in 1T-VSe 2 the CDW generates a much weaker … Webscanning tunneling microscopy (STM) to be restricted to the topmost layer. In addition, we performed transport measure-ments and found that the 2H-1T heterostructure device behaves as a metal without a Mott phase transition and exhibits a superconducting transition at 2.1 K, which is about 3 times higher than the T c of bulk 2H-TaS 2. Our work ... WebHere we present combined ARPES/STM spectroscopy and DFT simulation indicating that when TaSe 2 thickness is reduced from bulk to single-layer the electronic band structure changes significantly due to a reduced number of bands crossing E F in the normal state. Despite this evolution in electronic properties, however, the CDW remains unchanged. coy hopson
