Physicists at the University of Basel in Switzerland have been so focused on this capability that years of experimentation with the one-atom-thick sheets of carbon have led them to discover that it’s possible to direct the electrons in graphene across a predefined path.
In research published in the journal Nature Communications, the scientists discovered that when they stretched, or otherwise manipulated, the honeycomb structure of the graphene and applied both an electrical and magnetic field to it, they could direct the flow of electrons. This marks the first time that anyone has successfully switched the guidance of electrons on and off and guided them without any loss.
