1 Mar 2019 | | Abstract: | Atomically thin layers of 1T’-WTe$_2$ were recently shown to be a realization
of a quantum spin Hall (QSH) insulator, which is characterized by an insulating
interior and helical one-dimensional edge states. In the present study, we
place mono- and few-layers of WTe$_2$ on a van der Waals superconductor,
NbSe$_2$, to induce superconductivity into this system. Using scanning
tunneling microscopy and spectroscopy, we demonstrate the presence of a
proximity-induced superconducting gap in the WTe$_2$ for thicknesses up to 7
crystalline layers, the thickest sample measured. At the edge of the WTe$_2$
monolayer, we show that the superconducting gap coexists with the
characteristic signature of the QSH edge state. Taken together, these
observations provide strong evidence for proximity-induced superconductivity in
the QSH edge state in WTe$_2$, a crucial step towards realizing one-dimensional
topological superconductivity in this van der Waals material platform. | | Source: | arXiv, 1903.0493 | | Services: | Forum | Review | PDF | Favorites | |
