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.
