Semiconductor-superconductor hybrid nanowires are a leading material platform for the realization of Majo-rana zero modes. The semiconductors in previous studies are dominantly InAs or InSb. In this paper, we show the induced superconductivity in PbTe nanowires epitaxially coupled to a superconductor Pb. The Josephson junction devices based on this hybrid reveal a gate-tunable supercurrent in the open regime and a hard superconducting gap in the tunneling regime. By demonstrating the superconducting proximity effect, our result can enable Majorana searches and other applications, such as gate-tunable qubits in a new material platform.
