MIT's Hybrid Microchip To Overcome Silicon Size Barrier
schliz writes "MIT researchers have successfully embedded a gallium nitride layer onto silicon to create a hybrid microchip. The method could be further developed to combine other technologies such as spintronics and optoelectronics on a silicon chip. It is expected to be commercialized in a couple of years, and allow manufacturers to keep up with Moore's Law despite today's shrinking devices."
This is true, however, the real killer of cellphone battery life is the fact that the law of inverse squares is at play (power required is inversely proportional to the square of the distance between the source and destination.)
