Formation of YBa/sub 2/Cu/sub 3/O/sub 7-x//MgO and YBa/sub 2/Cu/sub 3/O/sub 7-x//Si thin film structure by laser pulse crystallisation and annealing

摘要

The results of the theoretical and experimental study of laser pulse crystallisation and annealing of the YBa/sub 2/Cu/sub 3/O/sub 7-x/ high-temperature superconducting amorphous layers are presented in the paper. It is determined that for each given film thickness and type of substrate there exists a optimal pressure of oxygen, laser pulse energy density, its duration and wavelength at which the conditions Of thermodynamic stability of the film compound is preserved.
