ABSTRACT
ZnO is presently a very “fashionable” material in semiconductor research for several reasons: It could provide an alternative material for light-emitting diodes (LEDs) in the green to UV spectral range. Heterostructures are possible with MgZnO for higher bandgap and CdZnO for lower bandgap. It is very easy to grow nanostructures from ZnO with a broad variety of morphologies. It is highly sensitive to chemicals, which makes it useful for sensors. It is a candidate for high-TC ferromagnetic semiconductors.
