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.
The ZnO nanostructures can be implemented in optoelectronic applications, piezoelectric
pressure sensors, Spintronic devices, transducers and biomedical applications [1-8]. Use of these
nanostructures, will also allow building of nanoscale nanosensors, nanocantilevers, field-effect
transistors and nanoresonators for a variety of military, homeland security and, commercial
applications. In this paper we review growth and characterization of ZnO nanowires on a variety
of substrates. Experimental results on the ZnO nanowires grown on GaN and SiC are presented
with growth morphology, structure analysis, and dimensionality control. We also discuss Raman
and micro-Raman spectroscopy for characterization of ZnO nanostructures.
