Abstract In the present work we report the fabrication, current density-voltage (J-V) characteristics, capacitance-voltage characteristics and impedance measurements of the n-ZnO nanoparticles/ p-CuPc hybrid junction. ZnO nanoparticles were synthesized by sol- gel method. The J-V characteristics clearly show the diode like behaviour. The junction behaviour has been investigated using surface topography (AFM), capacitance and electrical impedance studies. © 2014 The Authors. Elsevier Ltd. All rights reserved.

INTRODUCTION In recent days, inorganic - organic hybrid hetero-junctions have grabbed researcher's interest due to their significant role in many technological applications, e.g. photodiodes [1-3], photo detectors [4-6], light emitting diodes [7-10] and photovoltaics [11-14]. These hybrid structures have stimulated a lot of interests as they offer low cost and ease of processing with an added advantage of flexibility [15-17]. The p-n junctions based on Zinc Oxide (ZnO) and Copper Phthalocyanine (CuPc) has been fabricated using many experimental techniques and are widely reported in literature [18-20]. To the best of our knowledge, so far, very few reports are available on ZnO nanoparticles/CuPc hybrid hetero-junctions. * Corresponding author. Tel.: +0-000-000-0000 ; fax: +0-000-000-0000 .
