Graphene Sheets ... And Transistors

Two reports show that the promising carbon supermolecule can be prepared in larger films and doped with electrons to make transistors
Department: Science & Technology

Two new reports on graphene show that the electronically promising supermolecule, composed of a single layer of carbon atoms linked like chicken wire, can be prepared in large, uniform films and can be doped with electrons to make transistors. Graphene, which has taken the field of materials research by storm in the past couple of years, is usually synthesized in micrometer-sized bits by peeling off slices of three-dimensional graphite.
