Zinc and Zinc Oxide Nanowires Grown on PEDOT:PSS/SiO_2 Conductive Polymer Thin Films by Vapor Phase Transport Deposition

摘要

Easily available spin coating and vapor phase transport deposition techniques offer tremendous possibilities in fabricating inorganic/organic heterojunctions. We present here preliminary results from different thin film growth mechanisms including: i) PEDOT:PSS/Zn-nanowires/SiO_2, ii) Zn-nanowires/PEDOT:PSS/SiO_2, and iii) ZnO-nanowires/PEDOT:PSS/SiO_2. The preliminary scanning electron microscopy and energy dispersive spectroscopy results show that Zn nanowires bond better to the non-annealed PEDOT:PSS thin films. It was also found that ZnO nanowires grow homogeneously on annealed PEDOT:PSS surfaces with colloidal Au nanoparticles as bonding reaction catalysts.
