ZnO: growth, doping & processing

A review is given here of recent results in developing improved control of growth, doping, and fabrication processes for ZnO devices with possible applications to ultraviolet (UV) light emitters, spin functional devices, gas sensors, transparent electronics, and surface acoustic wave devices. ZnO can be grown on cheap substrates such as glass at relatively low temperatures and may have advantages over the GaN system in some of these applications.
