Research on Conductivity of Perovskite Oxide LaSrCoO AITranslate
Abstract AITranslate
La0.5Sr0.5CoO3 samples were prepared by solid-state reaction.The structure of the samples was analyzed by X-ray diffractometer and Raman spectrometer.XRD results indicate that La0.5Sr0.5CoO3 samples are of single-phase cubic perovskite structure.In the Raman spectrum,the peak caused by the rotation of oxygen octahedron and the secondary Raman peak formed by the vibration of Co—O bond angle and length can be observed.The energy band,density of states and partial density of states of La0.5Sr0.5CoO3 are calculated by the first-principles method.The results show that the conductivity of non-conductive pe-rovskite oxide LaCoO3 can be changed by doping Sr2+,which has guiding significance for the study of conductivity of perovskite oxide LaCoO3.
