Proximity-induced superconducting gap in the quantum spin Hall edge state of monolayer WTe${}_2$

Felix Lüpke, Dacen Waters, Sergio C. de la Barrera +5

The quantum spin Hall (QSH) state was recently demonstrated in monolayers of the transition metal dichalcogenide 1T'-WTe${}_2$ and is characterized by a band gap in the two-dimension…
