IBM researchers have built the first integrated circuit based on graphene, a breakthrough the company says could herald a future based on graphene wafers instead of silicon. The circuit, a 10 gigahertz frequency mixer, could give wireless devices greater range. At higher frequencies, the technology could someday allow law enforcement and medical personnel to see inside objects or people without the harmful effects of X-rays, according to IBM.
