Interfacial superconductivity induced by single-quintuple-layer Bi${}_2$Te${}_3$ on top of FeTe forming van-der-Waals heterostructure

We report the first clear observation of interfacial superconductivity on top of FeTe(FT) covered by one quintuple-layer Bi${}_2$Te${}_3$(BT) forming van-der-Waals heterojunction. Both…
