Product Description

Free-Standing GaN Substrates

1. What is GaN substrates
Gallium Nitride is one kind of wide-gap compound semiconductors. It is made with original HVPE method and wafer processing technology, which has been originally developed for many years.

2.Application
 
Laser diodes for Blu-ray Disc^™ players and light projectors
Future application: GaN PN-diode with high breakdown voltage over 3,000V and low on-resistance of 1mΩ·cm²
long-lived, efficient and reliable optoelectronic and electronic devices
high brightness LEDs for general lighting and high power, high frequency transistors for cellular phone base stations and defence applications.
