IBM Researchers announced on June 9, that they had designed his first high-speed circuits from graphene, an ultra-thin material that has a host of promising applications, from high-bandwidth communication to a new generation of low-cost smartphone and television displays. As reported in the journal 'Science', the IBM researchers describe a demonstration in which they deposited several layers of graphene on a silicon wafer, then created circuits based on graphene transistors and components known as inductors. They demonstrated frequency mixing up to speeds of 10 gigahertz. In the past, IBM has created stand-alone graphene transistors. It is the high speed circuit made by IBM.
