摘要：
The conductivity changes of Y1Ba2Cu3O7-delta thin films under r.f. field and white light treatment at 77 K and under laser irradiation at 300 K were studied. The modified films were found to recover partially after prolonged laser illumination. The kinetics of photoactivation was investigated. The observed nonthermally induced changes were associated with free carrier trapping and local disordering of the lattice.
