Semiconductor Rivalry Rages on in High-Temperature Chips

This article is part of our exclusive IEEE Journal Watch series in partnership with IEEE Xplore. Two semiconductors—silicon carbide and gallium nitride—are the rivals in a (quite literally) heated competition to make circuits capable of performing at the highest temperatures. Silicon carbide chips had taken the lead, operating at 600 °C. But gallium nitride, which possesses unique features that make it more functional at high temperatures, has n…
