Tip-induced or enhanced superconductivity: a way to detect topological superconductivity

Based on the cryogenic point contact system as shown in the schematic, the detection of tip-induced superconductivity (TISC) has been successfully realized in different topological materials. The observation of unconventional superconducting feature in these non-superconducting materials makes TISC a new way to investigate the topological superconductivity.112
