摘要：

Ultrasonic spray pyrolysis (USP) has been used to deposit thick films (up to 5 micron) of YBa2Cu3O7-x in situ on single-crystal oxide substrates, and single-crystal and textured polycrystalline Ag foil of different orientations. Epitaxial films grow with a strong level of in-plane texture on the single crystal oxide substrates ( < 3<degrees> full width at half maximum) and on (100) and (110) oriented Ag. Films grown under optimized conditions have onset T-c of 91 K with transition widths of similar to 6 K. The films are fully connected and J(c) are similar to 1.0 x 10(4) A cm(-2) at 77 K and similar to 5 x 10(5) A cm(-2) at 20 K.
