Nanoribbons of Tomorrow

Electrons flow through graphene at an astonishing 1 million meters per second, making it a natural for next-generation computer chips, communications equipment, and solar energy devices. However, to live up to its potential, graphene needs support. Scientists at the Oak Ridge National Laboratory are using the Cray XT™ “Jaguar” supercomputer, with a peak speed of 2.33 petaflops, for a computational study of what could be the ideal substrate for graphene – the compound boron nitride.
