摘要
This paper is concerned with high-T-c superconducting compounds produced by metal-organic chemical vapour deposition. The nanostructure of different types of interfaces yttria stabilized zirconia buffer/(1-102)-sapphire substrate, YBa2Cu3O7-x film/Y2O3 precipitates as well as YBa2Cu3O7-x film/(001)-NdGaO3, SrTiO3, and -MgO substrates - has been investigated by high resolution electron microscopy. The orientation relationships and the corresponding layer sequences across the interfaces have been determined with the aid of computer simulations.
