论文摘要
最近的实验表明，与高温超导体的接近性诱导石墨烯中非常规超导相关性。在这里，我们证明了这些相关性传播数百个纳米，从而可以独特地观察到$ d $ - 沃夫Andreev对yba $ _2 $ _2 $ cu $ _3 $ _3 $ o $ $ _7 $ _7 $ grapheene设备，这些设备的作用是fabry-pérotc的。该干扰显示是一系列明显的电导振荡，类似于最初由De Gennes-Sirt-James预测的传统金属 - 驱动器连接器所预测的电导振荡。目前的工作对于研究狄拉克材料中淋巴结超导性预期的外来定向效应至关重要。
Recent experiments have shown that proximity with high-temperature superconductors induces unconventional superconducting correlations in graphene. Here we demonstrate that those correlations propagate hundreds of nanometer, allowing for the unique observation of $d$-wave Andreev pair interferences in YBa$_2$Cu$_3$O$_7$-graphene devices that behave as a Fabry-Pérot cavity. The interferences show as a series of pronounced conductance oscillations analogous to those originally predicted by de Gennes--Saint-James for conventional metal-superconductor junctions. The present work is pivotal to the study of exotic directional effects expected for nodal superconductivity in Dirac materials.
