我们证明，通过单分子或分子整体的电子传输（通常基于金（Au）电极）可以通过将金与钼铼（MoRe）结合而扩展到超导电极。这种组合在金中产生了邻近效应超导性，温度至少为 4.6K，磁场强度为 6T，比之前报道的铝基超导纳米结有所改进。作为概念证明，我们展示了通过单个 Fe4 单分子磁体进行的三端超导输运测量。
We demonstrate that electronic transport through single molecules or molecular ensembles, commonly based on gold (Au) electrodes, can be extended to superconducting electrodes by combining gold with molybdenum-rhenium (MoRe). This combination induces proximity-effect superconductivity in the gold to temperatures of at least 4.6K and magnetic fields of 6 T, improving on previously reported aluminum based superconducting nanojunctions. As a proof of concept, we show three-terminal superconductive transport measurements through an individual Fe4 singlemolecule magnet.
