Organic Topological Insulator

Caption: University of Utah engineers demonstrated it is feasible to build the first organic materials that conduct electricity on their molecular edges, but act as an insulator inside. Called organic topological insulators, these materials are made from a thin molecular sheet (left) that resembles chicken wire and conducts electricity on its right edge (blue line) -- with the electrons carrying more information in the form of "up" spin. These new materials could be used to shuttle information at the speed of light in quantum computers due to the unique physical behavior a special class of electrons called Dirac fermions, depicted (right) in a plot of their energy and momentum.
