IBM Shows Smallest, Fastest Graphene Processor
“IBM on Thursday demonstrated its fastest graphene transistor, which can execute 155 billion cycles per second, which is about 50% faster than previous experimental transistors shown by the company’s researchers.
The transistor has a cut-off frequency of 155GHz, making it faster and more capable than the 100GHz graphene transistor shown by IBM in February last year, said Yu-Ming Lin, an IBM researcher.
The research also shows that high-performance, graphene-based transistors can be produced at low cost using standard semiconductor manufacturing processes, Lin said. That could pave the way for commercial production of graphene chips, though Lin could not say when manufacturing of such chips would begin.”
