Abstract

PbTiO3-covered ZnO nanorods were grown on Al2O3 by metalorganic chemical vapor deposition (MOCVD), and their crystalline orientation was investigated by x-ray diffraction (XRD). Structural analysis by scanning electron microscopy and XRD revealed that the hexagonal ZnO nanorods had -side facets. XRD analysis of PbTiO3 thin films on ZnO/Al2O3revealed that PbTiO3 was epitaxially grown on ZnO, showing 6 variants of crystallites with the c-axis tilted either 27o or 69o from the surface normal to the ZnO plane. Effective piezoelectric coefficients calculated for the 27o and 69o-crystallites using piezoresponse force microscopy confirm that deformation of nanorods and nanotubes contributed to the large electrically-induced strain along the radial direction.
