报告摘要：
Self-assembly has been approved to be a useful method to fabricate oxide thin films with a rich variety of periodic nanoscale patterns. Recent efforts have been focused on how to make the self-assembly controllable. In a film-on-substrate geometry, epitaxial composite films can be divided into two forms: horizontal and vertical. Success of the investigation critically replies on obtain and manipulation of these two architectures. In the present work, horizontally and vertically aligned nanostructures have been obtained in (YBa2Cu3O7-δ)0.5:(BaZrO3)0.5 and (BiFeO3)0.5:(Sm2O3)0.5 thin films respectively. And the manipulation between the vertical and horizontal architectures has been realized in (YBa2Cu3O7-δ)1-x:(BaZrO3)x systems by simply changing the composition of BaZrO3, which resulted from interplay between surface effect and bulk phase separation. The nanostructures dependent lattice constants, strain state, and electrical properties have also been investigated. More details will be presented in the talk.
