A promising new application of graphene has been described by researchers at MIT, Columbia University and IBM's T. J. Watson Research Center in the latest issue of Nature Photonics. It has been revealed that graphene in photo detectors could convert optical signals to electrical signals in integrated optoelectronic computer chips.
Light will be used by them instead of electricity to move data both within and between computer chips. This could drastically reduce the power consumption and heat production. These are the problems to engulf with increase in computational capacity.
