Abstract

Abstract: Vertically aligned 1D ZnO nanorods are grown on AZO seeded flexible stainless steel (SS) substrate using the hydrothermal method with different molar concentrations. Crystallographic properties of the grown ZnO nanorods are studied using XRD analysis. Morphological properties such as alignment and density of the nanorods is analyzed by FESEM analysis. Molecular properties of the grown ZnO nanorods is studied by analyzing the different vibrational modes obtained from Raman spectra. A heterojunction was formed by coating p-type organic polymer PEDOT:PSS on the grown ZnO nanorods. I-V characteristics of the heterojunction reveal diode like behavior. Relation between ideality factor ( n ), barrier height (Φ b ) of the heterojunction and the morphological properties of ZnO nanorods are discussed.
