论文摘要
探索拓扑量子计算的许多建议是基于在具有强旋转轨道耦合(SOC)的材料上构建的超导量子设备。对于这些设备,高度要求对超潮流的大小和空间分布的完全控制,但到目前为止一直难以捉摸。我们在BI2O2SE的纳米板上构建了接近型约瑟夫森连接,这是一种具有强大SOC的新的新兴半导体。通过电控,我们表明可以完全打开和关闭超电流,并且可以通过散装或边缘配置其真实空间途径。我们的工作将BI2O2SE作为一个有前途的平台,用于构建多功能混合超导设备以及寻找拓扑超导性。
Many proposals in exploring topological quantum computation are based on superconducting quantum devices constructed on materials with strong spin-orbit coupling (SOC). For these devices, a full control on both the magnitude and the spatial distribution of the supercurrent would be highly demanded, but has been elusive up to now. We constructed proximity-type Josephson junction on nanoplates of Bi2O2Se, a new emerging semiconductor with strong SOC. Through electrical gating, we show that the supercurrent can be fully turned ON and OFF, and its real-space pathways can be configured either through the bulk or along the edges. Our work demonstrates Bi2O2Se as a promising platform for constructing multifunctional hybrid superconducting devices as well as for searching for topological superconductivity.
