We characterize in situ grown parallel nanowires bridged by a superconducting island. The magnetic-field and temperature dependence of Coulomb blockade peaks measured across different pairs of nanowire ends suggest the presence of a subgap state extended over the hybrid parallel-nanowire island. Being gate-tunable, accessible by multiple terminals, and free of quasiparticle poisoning, these nanowires show promise for the implementation of several proposals that rely on parallel nanowire platforms.
我们对由超导岛桥接的原位生长平行纳米线进行了特性描述。通过测量不同纳米线末端对之间的库仑阻塞峰的磁场和温度依赖性，我们发现存在一个扩展到混合平行纳米线岛的亚带隙状态。这些纳米线具有可调谐的栅极、可通过多个端子访问且不受准粒子中毒的影响，因此有望实现依赖于平行纳米线平台的多项提案。
