用于单分子输运研究的超导氘-氘电极
Superconducting molybdenum-rhenium electrodes for single-molecule transport studies
摘要：
我们证明，通过单分子或分子系综，通常基于金（Au）电极的电子传输，可以扩展到超导电极结合金与铼-铼（MoRe）。这种组合在至少4.6开尔文的温度和6特斯拉的磁场下诱导金中的邻近效应超导电性，改善了之前报道的铝基超导纳米结。作为一个概念的证明，我们通过一个单独的Fe $_4$单分子磁体的三端电子输运测量。
英文摘要：
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 4.6 Kelvin and magnetic fields of 6 Tesla, improving on previously reported aluminum based superconducting nanojunctions. As a proof of concept, we show three-terminal superconductive transport measurements through an individual Fe$_4$ single-molecule magnet.
