Today’s Spotlight features an image, by Christine Daniloff/MIT using a device schematic courtesy of the researchers, of a new experimental concept on how to change the electronic state of graphene rapidly.
In normal conductive materials such as silver and copper, electric current flows with varying degrees of resistance, in the form of individual electrons that ping-pong off defects, dissipating energy as they go. Superconductors, by contrast, are so named for their remarkable ability to conduct electricity without resistance, by means of electrons that pair up and move through a material as one, generating no friction.
