Description:
Author(s): Yi-Min Zhang, Jia-Qi Fan, Wen-Lin Wang, Ding Zhang, Lili Wang, Wei Li, Ke He, Can-Li Song, Xu-Cun Ma, and Qi-Kun Xue A van der Waals heterostructure composed of graphitized SiC(0001) and the semiconductor SnSe 2 shows conventional BCS-type superconductivity that is firmly corroborated by the presence of quantized vortices under an external magnetic field. Interface engineering has revealed that the observed superconductivity originates from a two-dimensional electron gas confined to the very interface between SnSe 2 and graphene. [Phys. Rev.
