Investigation of the two-gap superconductivity in a few-layer ${mathrm{NbSe}}_{2}$-graphene heterojunction

Author(s): Tianyi Han, Junying Shen, Noah F. Q. Yuan, Jiangxiazi Lin, Zefei Wu, Yingying Wu, Shuigang Xu, Liheng An, Gen Long, Yuanwei Wang, Rolf Lortz, and Ning WangWe investigated the superconductivity in a few-layer NbSe2-graphene heterojunction by differential conductance spectroscopy. Because of the gate-tunable Fermi level of the few-layer graphene, used here as a tunneling electrode in a nano-point-contact spectroscopy setup, the differential conductance …[Phys. Rev.
