ZnO nanostructures for optoelectronic applications

In this Paper we present growth and characterization of ZnO nanowires on wideband gap substrates, such as SiC and GaN. Experimental results on the ZnO nanowires grown on p-SiC and p-GaN are presented with growth morphology, structure analysis, and dimensionality control. We also present experimental results on individual nanowires such as I-V measurements and UV sensitivity measurements with use of polymer coating on ZnO nanowires. The ZnO nanowires can be used for a variety of nanoscale optical and electronics applications.
