| Abstract: | The superconducting thin film YBCO has been prepared on single crystal substrate LaAlO3 using TFA-MOD method.The XRD method is used to characterize the construction of superconducting thin film YBCO and we get the best technology of deposition.The photoinduced properties of the film in different temperature and laser power have been studied.The YBCO film obviously has the relaxation phenomenon related with electronic system under the laser irradiation.This proves that the superconducting state of the YBCO f... |
