Researchers use graphene and CNTs to design an all-carbon spin logic gate

Researchers from the University of Texas in Dallas developed an all-carbon spin logic design for a switch that could be the basis of carbon spin logic devices.

The design is based on graphene nanoribbons and carbon nanotubes, which in conjunction can be used to create cascaded logic gates that are not physically linked. The communication between the gates happens via an electromagnetic wave (and does not use any physical movement of electrons), it is anticipated that communication will be much quicker - with the potential for terahertz clock speeds. The size of these logic gates will be much smaller than silicon based gates.
