Abstract

A spray pyrolysis system has been developed in which the use of airless atomisation and optical heating permits the deposition of thin film superconductors at growth surface temperatures exceeding 650*C. A comparison between centrifugal and hydrodynamic atomisation techniques shows that each possesses advantages and disadvantages for the deposition of thin films by this technique. The presence of a corona discharge has been found to be an essential ingredient for growth at high substrate temperatures.
