摘要：
Epitaxial Pb(Sc1/2Nb1/2)O-3 (PSN) and PbTiO3 (PT) superlattice thin films are processed on single-stepped SrTiO3 (001) substrates by the pulsed laser deposition (PLD) technique. SrRuO3 is deposited on the substrate as a bottom electrode layer for dielectric measurements. The orientation and structure of the films are determined by X-ray diffraction (XRD) method. Clear superlattice reflections are observed by XRD and the period of superlattice is calculated from difference of 2 theta of superlattice reflection. Real part of dielectric constant is about 350 at room temperature in the frequency range of 10(2)-10(5) Hz.
