Two-temperature model of nonequilibrium photoresponse of superconducting films to pulsed radiation
Abstract
Photoresponse of a superconducting film in the resistive state to pulsed radiation has been simulated making use of different effective temperatures to describe electron and phonon nonequilibrium distributions. Fitting of calculated voltage transients to experimental response signals gives electron-phonon interaction times at the transition temperature 3.5 ps, and 1.8 ps for YBa 2Cu 3O 7, and TlBa 2Ca 2Cu 3O 9 films respectively.
