Diamond, having the highest thermal conductivity of any known material, acts as a heat spreader that equalizes temperatures across the chip without introducing unwanted capacitances — a key drawback of prior approaches that grew diamond on top of GaN. Using a femtosecond laser and a precisely placed 20-micron die attach film, the team fabricated a power amplifier that outperformed all comparable devices in the literature. The technique is scalable for commercial production and has potential applications in 6G wireless, satellite communications, high-power radar, space systems, industrial drones, and data center power conversion. ## Full article daily.dev links to this article rather than hosting it.
