This is a unique book devoted to the important class of both oxide and nitride semiconductors. It covers processing, properties and applications of ZnO and GaN. The aim of this book is to provide the fundamental and technological issues for both ZnO and GaN. Materials properties, bulk growth, thin and thick films growth, control of polarity and application, nonpolar growth, structural defects, optical properties, electrical properties, nanostructures and the applications, and light emitters based on GaN and ZnO are treated succinctly. The unique format of touching both materials in each...

Semiconducting oxides and nitrides are becoming the most important s- jects in materials science. In particular, zinc oxide (ZnO), gallium nitride (GaN), and related compounds form a novel class of semiconductors which possess unique properties in terms of crystallography, crystal growth, op- cal properties, electrical properties, magnetic properties, and so forth. These uniquepropertiesmakethesematerialsquiteimportantinoptoelectronicsand electronics. Although for more than three decades oxide and nitride semiconductors have been known to possess unique properties, it is only recently that...

Zinc oxide, ZnO, has been attracting much attention because of its potential applications in photonic and optoelectronic devices. The notable properties of ZnO include direct band energy gap (Eg=3.37 eV at RT), large exciton binding energy of 60 meV, and strong cohesive energy of 1.89 eV. Recent reports on the lasing mechanism of ZnO have shown that ZnO is a promising photonic material for exciton devices in the wavelength ranging from blue to ultraviolet. It is well known that high quality materials are required for optoelectronic devices. At the current stage the problems in extending...
