Catalyst Patterning for Scalable CVD Growth of Graphene Nanoribbon IB-3034

Berkeley Lab scientist Yuegang Zhang and colleagues have developed a scalable technology for directly growing, with precise control over length, width, and position, graphene nanoribbons narrow enough to open band gaps needed for graphene electronic devices. The scientists used a chemical vapor deposition (CVD) technique that directly grows graphene on a thin layer of nickel (Ni) or other catalytic metal. Initially, a very thin layer (
