论文摘要
超导键式混合系统中的透明接触界面对于实现超导量子应用至关重要。在这里，我们研究了边缘接触工艺对超导铝 - 格拉烯连接的透明度的影响。我们通过促进边缘接触蚀刻工艺的化学成分来表现出超导 - 格雷烯连接的透明度的显着提高。我们的结果与最先进的石墨烯约瑟夫森连接相比。我们研究的发现有助于促进与边缘连接超导体 - 格拉烯连接的制造知识。
Transparent contact interfaces in superconductor-graphene hybrid systems are critical for realizing superconducting quantum applications. Here, we examine the effect of the edge-contact fabrication process on the transparency of the superconducting aluminum-graphene junction. We show significant improvement in the transparency of our superconductor-graphene junctions by promoting the chemical component of the edge contact etch process. Our results compare favorably with state-of-the-art graphene Josephson junctions. The findings of our study contribute to advancing the fabrication knowledge of edge-contacted superconductor-graphene junctions.
