MIT Combines GaN and Silicon Chips for Faster, Efficient Electronics Researchers from MIT and elsewhere have developed a new way to combine two types of chips: gallium nitride (GaN) and silicon-based CMOS chips into a single chip. The solution is cheaper, scalable, and more energy-efficient. Gallium nitride chips are not cheap or easy to work with, but they are faster and better at handling power. Silicon chips, on the other hand, are cheap and common but lack… |
