Superconductivity induced in InSb nanowires from new thin film superconductors

ORAL

Abstract

Previous research on superconductor-semiconductor nanowire devices focused heavily on aluminum and niobium alloys. Here we study superconductivity from new thin film superconductors in InSb nanowires. We observe hard superconducting gap and quantized conductance plateau at zero field. The magnetic field evolution of superconducting gap and of supercurrent are studied. New super-semi hybrid structures offering larger critical field and increased energy gap, as compared to aluminum, are interesting as they provide a powerful platform to study topological superconductivity, spin-orbit and Zeeman effects in Superconductor-Semiconductor Josephson Junctions.
