Gallium nitride (GaN) is emerging as a key power semiconductor for AI data centers, where rising rack power and the shift toward higher-voltage architectures are forcing suppliers to improve efficiency and power density. But despite rapidly expanding orders and falling costs, industry researchers say GaN remains at an early stage of adoption and is unlikely to displace silicon broadly for another two to three years.
