IBM has recently made a breakthrough by making graphene-based processors achieve a speed of 100 GHz. By comparison, silicon-based processors max out at 40 GHz. What’s more, an IBM researcher, Yu–Ming Lin, said that it is possible to fabricate graphene transistors with existing processes used in the semiconductor industries. This should speed up commercialization of the technology, if it ever happens. Just when things seem to look good, Lin said graphene-based microprocessors cannot substitute silicon-based microprocessors used in today’s computers, at least in the near future, due to some inherent properties in those materials. Graphene is possible to be used in analog transistors like signal processors and amplifiers, though.
