Zinc oxide nanorods

ZnO can be produced in a variety of architectures, such as nanowires, nanorods, nanobelts, etc. This project aims to combine ZnOnanorods, produced by chemical bath deposition, with a silicon substrate for white light emitting diodes. Chemical bath deposition is a cheap, environmentally friendly way of producing ZnO nanostructures. The challenge is to control the size, shape, density, orientation and alignment in a reproducible way. Our approach involves the control of the properties of a ZnO seed layer produced prior to the growth of the nanorods, as well as the use of diblock copolymers to produce nano-sized patterns on the substrate.
