Temperature-dependent behavior in the local structure of BaTiO3 nanocrystals†
Abstract
We use pair distribution function analysis of synchrotron X-ray total scattering data to inspect the local structure of BaTiO3 nanocrystals from 253 K < T < 413 K. The local structure consists of ca. r = 35 Å domains in which Ti4+ displacements have the same coherence length as the overall perovskite structure.
