Last year, research teams from IBM and the Massachusetts Institute of Technology both demonstrated graphene processors capable of frequencies around 26GHz. By comparison, silicon-based transistors of the same gate length (240 nanometers) have only been able to scale up to a clock rate of 40Ghz or so.

Application

1. Graphene is better suited for making analog transistors, such as signal processors and amplifiers. Today, such circuitry is largely made from GaAs (gallium arsenide), though GaAs offers nowhere near the same electron mobility.

2. Graphene processors could be the basis of superior signal processing componentry, improving the fidelity of audio and video recording, radar processing and medical imaging.

Advantages

1. Use of graphene for these interconnects could help extend the long run of performance improvements for silicon- based integrated circuit technology.

2. The advantage of graphene based chip is that it is practically possible to make three dimensional devices as graphene can easily be stacked and therefore making a massive storage device from it. Further being a mechanical device, graphene based chips will consume virtually no power and it is the biggest advantage of these chips.

3. Researchers in their lab has tested graphene from –75 to +200 degree Centigrade and observed no significant difference and therefore graphene based memory devices can be used also in hot processors and further there is no significant affect of radiation suggesting that these can also be used in extreme environment.
