Emergent superconductivity is observed in the local mesoscopic point‐contacts on the topological insulator Bi 2 Se 3 by applying a voltage pulse through the Ag contacts. The superconductivity can be erased with thermal cycles by warming up to high temperatures (300 K) and repeatedly induced by the voltage pulse at base temperature (1.9 K), suggesting a significance for designing new types of quantum devices.
