Abstract

Heteroepitaxial oxide-based nanocomposite films possessing a variety of functional properties have attracted tremendous research interest. Here, self-assembled vertically aligned nanocomposite (PrBaMnO):(CeO) (x = 0.2 and 0.5) films have been successfully grown on single-crystalline (001) (La,Sr)(Al,Ta)O substrates by the pulsed laser deposition technique. Self-assembling behavior of the nanocomposite films and atomic-scale interface structure between PrBaMnO matrix and CeO nanopillars have been investigated by advanced electron microscopy techniques. Two different orientation relationships, (001)[100]//(001)[1-10] and (001)[100]//(110)[1-10], form between PrBaMnO and CeO in the (PrBaMnO):(CeO) film along the film growth direction, which is essentially different from vertically aligned nanocomposite (PrBaMnO):(CeO) films having only (001)[100]//(001)[1-10] orientation relationship. Both coherent and semi-coherent PrBaMnO/CeO interface appear in the films. In contrast to semi-coherent interface with regular distribution of interfacial dislocations, interface reconstruction occurs at the coherent PrBaMnO/CeO interface. Our findings indicate that epitaxial strain imposed by the concentration of CeO in the nanocomposite films affects the self-assembling behavior of the vertically aligned nanocomposite (PrBaMnO):(CeO) films.

摘要

具有多种功能特性的异质外延氧化物基纳米复合薄膜引起了极大的研究兴趣。在此，通过脉冲激光沉积技术在单晶(001)(La,Sr)(Al,Ta)O衬底上成功生长了自组装垂直排列的纳米复合(PrBaMnO):(CeO)(x = 0.2和0.5)薄膜。利用先进的电子显微镜技术研究了纳米复合薄膜的自组装行为以及PrBaMnO基体与CeO纳米柱之间的原子尺度界面结构。在(PrBaMnO):(CeO)薄膜中，沿着薄膜生长方向，PrBaMnO与CeO之间形成了两种不同的取向关系，即(001)[100]//(001)[1 - 10]和(001)[100]//(110)[1 - 10]，这与仅具有(001)[100]//(001)[1 - 10]取向关系的垂直排列纳米复合(PrBaMnO):(CeO)薄膜有本质区别。薄膜中同时出现了共格和半共格的PrBaMnO/CeO界面。与具有规则分布界面位错的半共格界面不同，共格PrBaMnO/CeO界面发生了界面重构。我们的研究结果表明，纳米复合薄膜中CeO浓度所施加的外延应变会影响垂直排列纳米复合(PrBaMnO):(CeO)薄膜的自组装行为。
