窒化ガリウム市場の分析と予測

GALLIUM NITRIDE has been the subject of intensive research and product development for the past twelve years. Since 2000, GaN research activities have intensified around the world. The number of companies and research centers with GaN activity has increased to over 500 organizations in early 2005 from roughly 350 such organizations identified in 2000.

Blue, green, and white LED technology has continued its large-scale commercial growth resulting in revenues exceeding $3 billion in 2004. White LEDs are responsible for over 50% of the total GaN related LED market.

Future high-growth GaN devices include high-power LEDs for lighting, deep UV emitters, and laser diodes. The latter will be used in the next generation of optical storage technology and their development will be spurred by increasing availability of GaN substrates.
