GaN Wafer Characteristic
Gallium Nitride is one kind of wide-gap compound semiconductors. Gallium Nitride (GaN) substrate is
a high-quality single-crystal substrate. It is made with original HVPE method and wafer processing technology, which has been originally developed for 10+years in China. The features are high crystalline, good uniformity, and superior surface quality. GaN substrates are used for many kinds of applications, for white LED and LD(violet, blue and green) Furthermore, development has progressed for power and high frequency electronic device applications.
Forbidden band width (light emitting and absorption) cover the ultraviolet, visible light and infrared.
GaN can be used in many areas such as LED display, High-energy Detection and Imaging,
Laser Projection Display, Power Device, etc.
