Abstract:
We have studied the effects of substrate materials on the surface morphology, crystal quality and electrical properties of Bi 2 Sr 2 CaCu 2 O 8 superconducting epitaxial thin films grown on MgO (100), SrTiO 3 (100), NdGaO 3 (001), LaSrGaO 4 (001), LaAlO 3 (001) and YAlO 3 (001). Films grown on substrates with a large lattice mismatch have a lower T c and include a number of outgrowth grains. By contrast, films grown on substrates with a small lattice mismatch have a very smooth surface with almost no outgrowth grains or precipitates and have a higher T c . These results are interpreted in terms of the internal stress caused by the lattice mismatch between the film and substrate.
