Abstract

Differences in the thermal expansion between epitaxially grown films and the substrate result in a considerable strain of the deposit. Whenever a certain critical film thickness is exceeded the stress is inevitably relaxed by fracture. This problem is most prominent for YBa₂Cu₃O_7-δ films deposited on silicon substrates. We have studied the mechanism of crack formation in more detail, especially the part played by the surface morphology of the YBa₂Cu₃O_7-δ films. Theoretical limits are compared with experimental findings.
