  We present a report on hybrid InSb-Pb nanowires that combine high spin-orbit
coupling with a high critical field and a large superconducting gap. Material
characterization indicates the Pb layer of high crystal quality on the nanowire
side facets. Hard induced superconducting gaps and gate-tunable supercurrent
are observed in the hybrid nanowires. These results showcase the promising
potential of this material combination for a diverse range of applications in
hybrid quantum transport devices.
