Gate modulation and interface engineering on Coulomb blockade in open superconducting islands
Huading Song, Dong Pan, Runan Shang +4
Mesoscopic Coulomb blockade (MCB) is recognized as a phase-coherent variant of the conventional Coulomb blockade that arises in systems with open contacts. In open quantum dots, MC…
Strong enhancement of g-factor in PbTe-Pb hybrid nanowires
Shan Zhang, Wenyu Song, Zonglin Li +17
We report large Lande g-factors observed in PbTe-Pb hybrid nanowires. The g-factor can reach 83, significantly larger than those in bare PbTe nanowires (typically below 20). We att…
Anisotropy of PbTe nanowires with and without a superconductor
Zonglin Li, Wenyu Song, Shan Zhang +17
We investigate the anisotropic behaviors in PbTe and PbTe-Pb hybrid nanowires. In previous studies on PbTe, wire-to-wire variations in anisotropy indicate poor device control, posi…
Coulomb blockade in open superconducting islands on InAs nanowires
Huading Song, Zhaoyu Wang, Dong Pan +8
Electrons in closed systems can exhibit Coulomb blockade (CB) oscillations due to charge quantization. Here, we report CB oscillations in aluminum superconducting islands on InAs n…
