UCLA claims 300-GHz graphene transistors

摘要

Researchers and engineers at the University of California-Los Angeles have used a new fabrication method to create what they say is the highest-speed graphene transistors to date, with a cutoff frequency as high as 300 GHz (Reference 1). Researchers have in recent years heralded graphene, a one-atom-thick layer of graphitic carbon, as a possible replacement for silicon in semiconductors. The material involves some challenges, however.
