摘要

Epitaxial PbTiO_3 films of various thickness with and without Pt electrodes were grown on MgO(001) single crystal substrates at 650℃ by pulsed laser deposition. Their ferroelectric domain structures were investigated extensively by two-dimensional reciprocal space mapping using synchrotron X-ray. Ferroelectric domain structures and their evolution of the epitaxial PbTiO_3 films with no electrode layer and with a Pt electrode layer between the film and the MgO(001) substrate were found to be quite different. The equilibrium domain structures in epitaxial PbTiO_3 thin films are analyzed by the finite element method using a commercial package, ABAQUS. The results of FEM simulation were found to be consistent with the experimental observation. This means that the sign and magnitude of initial misfit strain and the degree of its relaxation by interfacial dislocation at the deposition temperature influence critically on the domain evolution and final domain structure in epitaxial PbTiO_3 thin films.
