ABSTRACT:
A process for making a superconducting, Pb-doped, 2:2:2:3 BiSrCaCuO thin film includes heating deposited thin film material at between 1083K and 1103K for no more than 20 minutes in oxygen with a flow rate of 500 sccm, followed by quenching the material in air to room temperature, heating the material in air between 1103K and 1143K for no more than 40 minutes and finally quenching the material in air to room temperature.
