- Gallium nitride (GaN) has been attracted as a substrate for blue luminescent diode. The conventional method to grow single crystal GaN is using gallium melts on the sapphire substrate under ultra high temperature and ultra pressure. ... Hitherto, this research group obtained one mm size crystals in 1996, and subsequently obtained 6mm size gallium nitride crystals in 2001. In these processes, sodium azide (NaN3) and metal gallium were used. ...
- "Gallium nitride is a material that few people outside of the electronics field have even heard of," said ONR Program Officer John Zolper. "But it may turn out to be one of the most important materials of the new millennium." During the last five years, some stunning breakthroughs in the production of blue and green lasers and light emitting diodes, or LEDs, with reliably extended lifetimes generated excitement in scientific circles about these nitride-based materials. ... Also, new radar technology that can search, detect, and track smaller and faster targets in the littoral, or coastal, zones of the world where future Naval conflicts are expected to occur is a driving force behind ONRs long-term support of gallium nitride technology.
