Local atomic geometry and Ti 1s near-edge spectra in PbTiO(3) and SrTiO(3)

We study Ti 1s near-edge spectroscopy in PbTiO(3) at various temperatures above and below its tetragonal-to-cubic phase transition, and in SrTiO(3) at room temperature. Ab initio molecular dynamics (AIMD) runs on 80-atom supercells are used to determine the average internal coordinates and their flu...
