Photoinduced changes of the electrical conductivity in modified YBCO thin films.

Author(s) : TYUTYUNDZHIEV N., KANEV S.

Type of article: Article

Summary

The conductivity changes of YBCO(-) thin films under radio-frequency 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.
