Electrochemical studies on two-dimensional ZnInO nanoplates for organic-inorganic hybrid photodiode related applications

Abstract

An ultra low cost route has been established to fabricate organic-inorganic hybrid p-n junctions via chemical in-situ polymerization of organic monomers on traditionally drop casted inorganic deposits. In this regard, ZnInO nanoplate-like structures were synthesized through a facile solution based chemical approach and their structural property was studied using X-ray diffraction patterns. The nature of charge carriers and donor density in ZnInO made electrodes were studied using electrochemical impedance spectroscopy. The dissemination of polymer matrices on the ZnInO nanoplates was examined through scanning electron microscopy. The current-voltage characteristics obtained across the polypyrrole/ZnInO made hybrid structures revealed an improved rectifying behaviour under illuminated conditions. The mechanism behind the drastic decrease in resistance values that substantiates the improved electron transfer characteristics across the organic-inorganic structures was studied through cyclic voltammetric measurements.
