The structure, electrical and sensing properties for CO of ...

Abstract The perovskite structure of La Sr Co 1− x Ni x O 3− δ film can be formed in a wide range between 0≦ x ≦ by the dipping method. The distortion of the perovskite structure is described with changing Ni content. The influence of Ni ions which replaced the Co ions on B-sites can be directly observed from its electrical and sensing properties to CO gas.
