We study the outer atomic surfaces of a series of perovskite-based ceramics using low energy ion scattering spectroscopy. After high temperature treatment, segregated A-site (or acceptor substituent) cations dominate the outer surfaces with no B-site cations detected. We also find evidence of an associated B-cation enriched region below the surface.
