Abstract
Lead titanate thin films and fibers were prepared by sol-gel technique and the phase formation behavior, surface morphology and the effect of strain on the microstructural features of these samples was investigated. The x-ray and micro-Raman scattering results indicate the formation of the tetragonal perovskite phase in both films and fibers. The analysis of the Raman phonon modes reveals that the film is more stressed than the fibers. The variation of stress has been correlated to the microstructural features in these structures.
