Georgia Tech researchers are considering a solution that would allow for one terabit of data to be uploaded in – wait for it – one second. The wire, composed of graphene, would be able to transfer this amount over one or two meters with a graphene antenna, with up to 100 terabits a second being possible the closer you get. Graphene, which is essentially a sheet of carbon, is only one atom thick. Its honeycomb structure allows electrons to move through it up to 500 times faster than they would through silicon, and with almost no resistance.
In order to create an antenna, the graphene could be shaped into tiny, thin strips – just one micrometer long and up to one hundred nanometers wide is all that would be needed. This is the size at which data can be transmitted and received at terahertz frequency. The electromagnetic waves can interact with plasmonic waves in this frequency to send and receive data. A wireless connection using graphene could make wireless connections between chip components that much faster, because of the fact that graphene antennas can be created on a much smaller scale than wire antennas.
