ABSTRACT
As mentioned already, ZnO bulk crystals have been grown by a number of methods. In general, growth of bulk ZnO crystals is mainly implemented by three methods: hydrothermal [2], vapor phase [3,4], and melt growth [5]. The low super-saturation of the solution during hydrothermal reaction favors crystal growth. As a result, its application to the large-scale single crystals is quite suitable. A method for producing very-high-quality bulk ZnO wafers is based on vapor transport. Additionally, another method for producing bulk ZnO is that of melt growth, which is adopted by Cermet, Inc. [5]. The Cermet, Inc. melt method is based on a pressurized induction melting apparatus.
