[ieee] First Graphene Integrated Circuit

post #1 of 10

Quote:
9 June 2011—IBM researchers have built the first integrated circuit (IC) based on a graphene transistor—another step toward overcoming the limits of silicon and a potential path to flexible electronics.

The circuit, built on a wafer of silicon carbide, consists of field-effect transistors (FETs) made of graphene, a highly conductive chicken-wire-like arrangement of carbon that's a single atomic layer thick. The IC also includes metallic structures, such as on-chip inductors and the transistors' sources and drains. The work is described in this week's issue of Science. Researchers say that graphene, which has the potential to make transistors that operate at terahertz speeds, could one day supplant silicon as the basis for computer chips.

This is just one IC, they've still got a lot to do, but it is a step forward.

It is a repost of the story in general; but, IEEE gives a lot more detail than the original link. So, thank you for posting this link.

One remarkable feature is that the performance of the device didn't change very much when its temperature went from 300 to 400 kelvins (about 27 °C to 127 °C). That means a graphene circuit won't have to be overdesigned to compensate for temperature changes, potentially leading to a less-complex and less-expensive circuit.
Ok, that is even more Impressive than I thought graphene was.
