Voltage stability under current bias in superconducting microbridges

In superconducting films, the dissipative flux flow state plays a crucial role in the stability of those devices that operate under bias current whose value is very close to the critical current value, such as superconducting electronics and superconducting single particle/photon detectors. Therefore, we study the voltage stability versus electrical current transport by proper current-voltage measurement modes in superconducting films, investigating the effects of ion irradiation on the relevant current parameters
