Phase-slip shot noise caused by the current induced motion of vortices across a superconducting film can lead to excess noise in superconducting bolometers. The occurrence of this noise and its influence on the electrical noise equivalent power can be directly related to parameters such as the thermal conductance, sheet resistance, and bias current. The existence of phase slip shot noise may also explain discrepancies among previous researchers.
