A team of scientists and engineers from Stanford, the University of Florida, and Lawrence Livermore National Laboratory is the first to create one of two basic types of semiconductors using an exotic, new, one-atom-thick material called graphene. The findings could help open the door to computer chips that are not only smaller and hold more memory -- but are also more adept at uploading large files, downloading movies, and other data- and communication-intensive tasks.
