A look at gallium nitride chips, which could replace silicon chips in a growing range of electronics and be produced in conventional fabs, unlike graphene chips
Christopher Mims / Wall Street Journal : Tweets: @wsj , @amcafee , @raju , @wsj , and @gyude_moore Tweets: @wsj : Meet gallium, the weird metal that melts in your hand and is powering a revolution in electronics https://www.wsj.com/... Andrew McAfee / @amcafee : “you can now buy a GaN charger for $20 to $70 that is better in every way than the ones that came with your gadgets.” https://www.wsj.com/... #MorefromLess THREAD time! Raju Narisetti / @raju : On Gallium An industrial waste byproduct of extracting aluminum from rock, gallium has such a low melting temperature that it turns into a runny, silvery-white liquid when you hold it in your hand. On its own, it isn't terribly useful. https://www.wsj.com/...? @WSJ @wsj : Gallium, once an industrial-waste product, is transforming our increasingly electrified world https://www.wsj.com/... W. Gyude Moore / @gyude_moore : Not long ago GaN was a “mere laboratory curiosity. Then the Pentagon got interested... Beginning around 2000, funding from Darpa,...drove the experimentation required to overcome many of the hurdles to its commercialization...” https://www.wsj.com/...
