Abstract

Epitaxial SrBi2Ta2O9 (SBT) thin films with well-defined (116) orientation have been grown by pulsed laser deposition on Si(100) substrates covered with an yttria-stabilized ZrO2 (YSZ) buffer layer and an epitaxial layer of electrically conductive SrRuO3. Studies on the in-plane crystallographic relations between SrRuO3 and YSZ revealed a rectangle-on-cube epitaxy with respect to the substrate. X-ray diffraction pole figure measurements revealed well-defined orientation relations, viz. SBT(116)∥SrRuO3(110)∥YSZ(100)∥Si(100), SBT[110]∥SrRuO3[001], and SrRuO3[111]∥YSZ[110]∥Si[110].
