论文摘要
半导体 - 渗透杂种纳米线是实现Majorana零模式的领先材料平台。先前研究中的半导体主要是INA或INSB。在这项工作中，我们显示了与超导体PB耦合的PBTE纳米线中诱导的超导性。基于此混合动力车的约瑟夫森连接装置揭示了开放式策略中的栅极可调超电流，并且在隧道方案中有硬性超导差距。通过证明超导接近效应，我们的结果可以在新的半导体系统中启用Majorana搜索和其他应用，例如栅极可调量子。
Semiconductor-superconductor hybrid nanowires are a leading material platform for the realization of Majorana zero modes. The semiconductors in previous studies are dominantly InAs or InSb. In this work, we show the induced superconductivity in a PbTe nanowire epitaxially coupled to a superconductor Pb. The Josephson junction device based on this hybrid reveals a gate-tunable supercurrent in the open regime and a hard superconducting gap in the tunneling regime. By demonstrating the superconducting proximity effect, our result can enable Majorana searches and other applications like gate-tunable qubits in a new semiconductor system.
