- III-Nitride(GaN,AlN,InN)
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.
Application
GaN can be used in many areas such as LED display, High-energy
Detection and Imaging,
Laser Projection Display, Power Device, etc.
