摘要：

To attempt to solve the important technological problem of developing techniques for the growth of thick film YBa2Cu3O7-delta layers on polycrystalline Al2O3 substrates, we investigated a number of different barrier layer systems. In general these do not provide high current capacity structures; however, by the use of silver doping and sapphire substrates, critical current densities of 200 A cm-2 were obtained. While this is more than an order of magnitude less than comparable films on yttrium-stabilized zirconia, it represents a significant step towards the fabrication of films on the technologically more attractive substrate material.
