Electrochemical Deposition Mechanism for ZnO Nanorods: Diffusion Coefficient and Growth Models

Abstract

Fabrication of nanostructured ZnO thin films is a critical processfor many applications based on semiconductor devices. So on understandingof the electrochemical deposition mechanism is also fundamental forknowing the optimal conditions on growth of ZnO nanorods by electrodeposition.In this paper the electrochemical mechanism for ZnO nanorods formationis studied. Results are based on the evolution of the diffusion coefficientusing the Cotrell equation, and different growth models proposedby Scharifcker and Hills for nucleation and growth.
