Abstract
In-situ process are provided for 1) depositing on a substrate a crystalline thin film of a high temperature superconducting oxide by exposing the back surface of the substrate, i.e., the surface of the substrate opposite the surface on which the thin film is deposited, to radiation from a direct radiant heat source, thereby heating the substrate to the desired growth temperature, and maintaining the radiation and thereby the desired growth temperature during the deposition of the thin film, and 2) depositing a crystalline thin film of high temperature superconducting oxides onto both the front and back surfaces of a substrate.
