Diamond Quanta Selected by HAX
"Power electronics are shifting to wide-bandgap materials to hit performance targets silicon simply can't reach, but every one of those gains is capped by how quickly you can pull heat off the device. Diamond solves that better than anything we've come across, and Diamond Quanta is one of the few teams actually engineering it for manufacturable, real-world use”
