Gallium Nitride is taking over the world!
Well, maybe not the entire world but it is getting seriously important! I enjoyed the article at http://venturebeat.com/2015/04/02/move-over-silicon-gallium-nitride-chips-are-taking-over/ from which I paste: Above: Alex Lidow, CEO of Efficient Power Conversion Image Credit: Dean Takahashi ilicon chips have had a decades-long run as the foundation for modern electronics. But a new kind of chip, based on the compound material gallium nitride (GaN), promises to unseat silicon because it has higher performance, less power consumption, and lower cost. That might sound crazy, given the economies of scale for silicon, which has been an almost perfect semiconductor device that can both conduct or block electrical signals. Many people scoffed in early years at alternative materials such as gallium arsenide, which proved to be too expensive. Gallium nitride’s assault on silicon is just in time for the 50th anniversary of Moore’s Law, the prediction by Intel chairman emeritus G...
