Аннотация:Epitaxial thin films of CeO2 and Ce1−xRxO2− y (R=Y, Nd; x=0–0.32) on R-sapphire were prepared by band flash evaporation MOCVD. It was demonstrated that the smoothness of the films can be improved by a decrease of deposition rate and by post deposition annealing at 1000 °C. The lattice match of buffer layers with R-Al2O3 and YBa2Cu3O7−δ was improved by doping of ceria yttrium and neodymium correspondingly. A bilayer structure Ce0.7Nd0.3O2− y/Ce0.68Y0.32O2 − y/R-Al2O3 is proposed as potential substrate material for YBa2Cu3O7 − 6 deposition
