Growth of highly oriented ZnO nanowires on GaN substrates for electronic and optical sensor applications

In this Paper we present growth and characterization results of highly oriented ZnO nanowires grown on wide bandgap GaN substrates. Experimental results on the ZnO nanowires grown on p-GaN are presented with growth morphology and dimensionality control. We also present experimental results on these nanowire arrays such as I-V measurements and UV sensitivity measurements. The ZnO nanowires can be used for a variety of nanoscale optical and electronics applications.
