Abstract

Superconducting thin films of high Tc cuprates have been prepared using wet chemical precursors, which are spun on a substrate, pyrolyzed and heat-treated. This new method is simple and inexpensive, and is easily amenable to scale-up to cover large areas. No vacuum equipment is required. The technique allows easy manipulation of film stoichiometry and gives films having excellent compositional uniformity. A 1600 A film of Ba2YCu3O7 prepared by this method had a room temperature resistivity of 500/xfzcm, Tc/(onset) of 90K, and R=0 at 58K. The preparation and electrical and microstructural characterization of thin films of Ba2YCu3O7 and other high TC cuprates will be discussed.
