Synthesis and Characterization of In-Doped ZnO Planar Superlattice Nanoribbons

Abstract

Superlattice nanowires and nanoribbons are categorized as axial superlattice nanowires and lateral superlattice and planar superlattice nanoribbons according to their superlattice stacking directions. We analyze the dependence of X-ray diffraction (XRD) and select-area electron diffraction results on the different diffraction configurations of these superlattice structures. By use of the analysis, we have identified the formation of planar superlattice structures in In-doped ZnO nanoribbons by XRD and cross section transmission electron microscopy investigations. The In-doped ZnO superlattice nanoribbons are formed by alternately stacking layers of In/Zn−O and In−O along ZnO (001) direction, resulting in a nanoribbon with (001) polar surface as its wide surface.
