Abstract

Abstract: High-energy X-ray diffraction study was performed on lead titanate (PbTiO3 ). Short-range order structure was revealed using atomic pair-distribution function (PDF) method. In the high-temperature cubic phase, there is a large deviation between local and average structure. Especially, Pb atoms deviated from the cubic lattice framework, but establish Pb-O-Pb random network.
