An analytical approach to the thermal instability of superconducting films under high current densities

open access: yes, 2011
Using the Green's function of the 3D heat equation, we develop an analytical account of the thermal behaviour of superconducting films subjected to electrical currents larger than their critical current in the absence of an applied magnetic field.
