Supercurrent through a single transverse mode in nanowire Josephson junctions
B. Zhang, Z. Li, H. Wu +6
Hybrid superconductor-semiconductor materials are fueling research in mesoscopic physics and quantum technology. Recently demonstrated smooth -Sn superconductor shells, due to t…
Missing odd-order Shapiro steps do not uniquely indicate fractional Josephson effect
P. Zhang, S. Mudi, M. Pendharkar +10
Topological superconductivity is expected to spur Majorana zero modes -- exotic states that are also considered a quantum technology asset. Fractional Josephson effect is their man…
Large Second-Order Josephson Effect in Planar Superconductor-Semiconductor Junctions
P. Zhang, A. Zarassi, L. Jarjat +12
We investigate the current-phase relations of Al/InAs-quantum well planar Josephson junctions fabricated using nanowire shadowing technique. Based on several experiments, we conclu…
Parity-preserving and magnetic field resilient superconductivity in indium antimonide nanowires with tin shells
M. Pendharkar, B. Zhang, H. Wu +14
We study bottom-up grown semiconductor indium antimonide nanowires that are coated with shells of tin. The shells are uniform in thickness. The interface between Sn and InSb is abr…
Erasing odd-parity states in semiconductor quantum dots coupled to superconductors
Z. Su, R. Zitko, P. Zhang +9
Quantum dots are gate-defined within InSb nanowires, in proximity to NbTiN superconducting contacts. As the coupling between the dot and the superconductor is increased, the odd-pa…
Ferroelectric switched all-metallic-oxide - junctions
J. Yuan, H. Wu, L. Zhao +13
We report the first formation of the metallic - junctions, the ferroelectric (Ba,Sr)TiO (BST) switched optimally electron-doped (-type) metallic T'-phase superconducto…
