When integrated into optoelectronic devices, it is enough to have a single atom in the wrong place at the interface (represented by the glowing blue color) to jeopardize their performance.

Theoretical all-carbon circuits
Engineers at the University of Texas at Dallas, the University of Illinois at Urbana-Champaign, the University of Central Florida, and Northwestern University designed a novel computing system made solely from carbon.

“The concept brings together an assortment of existing nanoscale technologies and combines them in a new way,” said Dr. Joseph S. Friedman, assistant professor of electrical and computer engineering at UT Dallas. The resulting all-carbon spin logic proposal is a computing system that Friedman believes could be made smaller than silicon transistors, with increased performance.

In the all-carbon spintronic circuit design, electrons moving through carbon nanotubes create a magnetic field that affects the flow of current in a nearby nanoribbon, providing cascaded logic gates that are not physically connected.
