I.B.M. Researchers Create High-Speed Graphene Circuits

by www.laptop-battery.sg on Jun 10, 2011


The I.B.M. Advance, which the researchers reported in the sphere of the journal Science, is a circuit accepted to the same degree a broadband frequency mixer with the aim of was built on a wafer of silicon. Widely used in the sphere of all kinds of communications products, the circuits swing signals from single frequency to an alternative.

In the sphere of the Science paper, the I.B.M. Researchers illustrate a demonstration in the sphere of which they deposited several layers of graphene on a silicon wafer, followed by formed circuits based on graphene transistors and components accepted to the same degree inductors. They demonstrated frequency mixing up to speeds of 10 gigahertz.

In the sphere of the times of yore I.B.M. Has formed stand-alone graphene transistors, but not complete electronic circuits.

Scientists began making flakes of graphene, an atomic-scale lattice of carbon atoms, in the sphere of the 1970s. They give regularly...Read More >>
