Popis: Organic-Inorganic hybrid materials have remained an active field of research both from the point of understanding the interfaces and for device purpose. In the present work, Zinc Oxide (ZnO) - Polyaniline (PANI) interface obtained by drop casting PANI nanofibres on sputtered ZnO thin film is investigated. The study of layer by layer deposition of organic and inorganic materials to form interface, is a very important issue related to carrier transport, charge separation, structural connectivity and interfacial defects. I-V characteristics were performed for different thickness of the underlying ZnO layer. The effect of temperature on the I-V characteristics is also investigated. Hall measurements were performed to estimate the charge carrier concentration of the n-ZnO and the p-PANI. Morphology and thickness of the interface was studied using SEM imaging technique. These interfaces could be explored for different applications in areas like sensors and optoelectronics.
