China Just Made the World's Fastest Transistor and It Is Not Made of Silicon
The new transistor runs 40% faster and uses less power.
With a slender sheet of lab-grown bismuth and an architecture unlike anything inside today’s silicon chips, they’ve built what they call the world’s fastest and most efficient transistor. “If chip innovations based on existing materials are considered a ‘short cut’, then our development of 2D material-based transistors is akin to ‘changing lanes’,” Hailin Peng, professor of chemistry at Peking University and the study’s lead author, told SCMP. “This work demonstrates that 2D GAAFETs do exhibit comparable performance and energy efficiency to commercial silicon-based transistors,” the researchers wrote, “making them a promising candidate for the next technology node.”
