摘要：

The transport properties of high-temperature superconductor (HTSC) thin films are closely related to the crystallographic growth quality. Three examples are presented for such relationships. In YBaCuO films on SrTiO3 the critical current density decreases exponentially with increasing mosaic spread. For BiSrCaCuO-films (2212-phase) it is shown that the superior in-plane growth quality on SrTiO3 results in higher j(c)-values. (7.10(5) A/cm2) as compared to those on MgO (6.10(4) A/cm2). In films of different growth orientation (e.g. a-axis films) the specially needed deposition conditions also influence the properties.
