Abstract Structure change resulting from oxygen vacancies can strongly influence the chemical and physical properties of transition metal oxides, leading to new functionalities for novel electronic devices. In this work, by annealing LaBaCo2O6-δ epitaxial films in different atmospheres, e.g., O2, N2 and H2, we deduce that the concentration of oxygen vacancies and the stress in the film lattice imposed by the substrate play an important role in the ordering of oxygen vacancies in the LaBaCo2O6-δ epitaxial films. Moreover, the structure changes resulting from the vacancy ordering have a direct influence on the electrical and optical properties of the epitaxial films.

LaBaCo2O6-δ 外延薄膜中氧空位的排序

摘要 氧空位引起的结构变化会强烈影响过渡金属氧化物的化学和物理性质，从而为新型电子器件带来新的功能。在这项工作中，通过在不同的气氛中对 LaBaCo2O6-δ 外延薄膜进行退火，例如 O2、N2 和 H2，我们推断氧空位的浓度和衬底施加的薄膜晶格中的应力在LaBaCo2O6-δ 外延薄膜中的氧空位。此外，空位排列引起的结构变化对外延膜的电学和光学性质有直接影响。
