Superconducting-like behavior of Bi/Bi2O3 interface

•Bi/Bi2O3 interface was formed by surface oxidation of Bi.•Magnetic susceptibility and electrical resistance of the interface were studied.•Superconductivity at 15–35 K of the Bi/Bi2O3 interfaces was observed.•The superconducting interface is instable under normal conditions. Metastable superconduct...
