In development for decades, gallium nitride (GaN) has suddenly emerged from the labs to become a primary component in higher-end LEDs. GaN is being used to make blue LEDs, thereby enabling next-generation Blu-Ray DVDs to hit the marketplace. There is also a sudden interest in developing standalone GaN-based discrete parts. Targeted to replace conventional gallium-arsenide (GaAs) technology, GaN claims to possess a large heat capacity and wide bandgap properties, making it ideal for a range of fast-growing consumer and communications markets. The military is quietly pouring millions of dollars in GaN R&D and contracts. Read about it on Automotive DesignLine.
