Abstract

Surface structure of PbTiO₃ was studied using in situ x-ray scattering measurements and equilibrium surface structure was observed in vapor phase under defined cation stoichiometry. The samples were grown in an organometallic vapor phase epitaxy system on SrTiO₃ substrates. Samples were maintained at high temperature and flowing tetraethyl lead for in situ x-ray characterization. Results indicated the presence of a single layer of an antiferrodistortive structure in the atomic structure of the c(2×2) phase with oxygen cages counter-rotated by 10^° about the titanium ions.
