Abstract

We investigate the Raman scattering and electron diffraction (ED) for the nominal composition of Bi1.8Pb0.2Sr2-xCuOy, samples. It is found that the Sr vacancies bring about the distortion of Sr-O bond as well as the reduction of the incommensurate modulation with decreasing Sr content in Bi1.8Pb0.2Sr2-xCuOy, samples. Our analysis indicates that the characteristics in Raman scattering spectra can be explained well by the crystal misfit model.
