绝大多数超导体中的电子配对遵循巴丁-库珀-施里弗超导理论，该理论描述了电子在具有反波对称性的单重态中凝聚成具有反平行自旋的电子对。在单层石墨烯（SLG）中预测了非传统的超导性，电子配对具有ap波或手性波对称性，这取决于费米能量相对于狄拉克点的位置。通过将SLG放置在电子掺杂的（非手性）d波超导体上，并进行局部扫描隧道显微镜和光谱学，在这里，我们展示了SLG中p波触发的超导态密度的证据。在SLG中实现非常规超导电性为利用相变温度高于4.2K的二维材料发展p波超导性提供了一条令人兴奋的新途径。
Electron pairing in the vast majority of superconductors follows the Bardeen–Cooper–Schrieffer theory of superconductivity, which describes the condensation of electrons into pairs with antiparallel spins in a singlet state with ans-wave symmetry. Unconventional superconductivity was predicted in single-layer graphene (SLG), with the electrons pairing with ap-wave or chirald-wave symmetry, depending on the position of the Fermi energy with respect to the Dirac point. By placing SLG on an electron-doped (non-chiral)d-wave superconductor and performing local scanning tunnelling microscopy and spectroscopy, here we show evidence for ap-wave triggered superconducting density of states in SLG. The realization of unconventional superconductivity in SLG offers an exciting new route for the development ofp-wave superconductivity using two-dimensional materials with transition temperatures above 4.2 K.
