Episode 18 of The Hardware Podcast explores gallium nitride (GaN) power semiconductors — the material quietly replacing silicon in chargers, data centers, and electric vehicles. Lucas and Luna unpack why GaN switches faster and wastes less heat than traditional silicon MOSFETs, using a concrete example: a 65-watt USB-C charger that shrank from a brick to a deck of cards. They discuss the physics advantage — wider bandgap, higher critical field — and the real-world friction: manufacturing yield, substrate cost, and the slow pace of ecosystem adoption.
