ABSTRACT

With a wide bandgap of 3.37 eV and a large exciton binding energy of 60meV at room temperature, zinc oxide (ZnO), like GaN, is considered as an important material for blue and ultra-violet optical devices. Its research interest arisen again since 1957, the New Jersey Zinc Company published a book entitled “Zinc Oxide Rediscovered” to promote the material’s “frontier” properties (such as semiconductor, luminescent, catalytic, ferrite, photoconductive, and photochemical properties) and illustrative applications. Recently, research focused mainly on fabrication of high quality single crystals and epitaxial layers, in order to fully realize ZnObased electronic and optoelectronic devices.
