Abstract

Several attempts have been made by different groups to grow (110) YBa2Cu3O7−δ thin films on (110) substrates. In most of the cases, both (103) and (110) orientations of YBa2Cu3O7−δ have been found in the film. The substrate temperature during deposition is one of the major factors that determines the crystal orientation of the YBa2Cu3O7−δ. In our experiment, effort is made to examine the influence of the initial substrate temperature from 595 °C to 660 °C on the relative amount of (110) and (103) oriented grains. The orientations are determined by x-ray analysis with a Weissenberg camera. The amount of (103) oriented YBa2Cu3O7−δ is reduced systematically with decreasing substrate temperature. At the lowest deposition temperatures we find only (110) oriented growth.
