From: Ferroelectric triggering of carbon monoxide adsorption on lead zirco-titanate (001) surfaces
Evidence of the interplay between the initial polarization state and the degree of CO adsorbed on the surface (a) C 1s, photon energy 400 eV; (b) Pb 4f7/2, photon energy 260 eV; (c) Zr 3d, photon energy 260 eV (d) Ti 2p3/2, photon energy 600 eV; (e) O 1s, photon energy 600 eV (f) valence band, photon energy 100 eV; (g,h) represent models of interface band diagrams for P(+) and P(−) polarizations.
