Graphene Ribbons
Abstract:
TYING TOGETHER materials science and chemistry, scientists have developed a chemical method for making carbon ribbons less than 10 nm wide and just one atom thick (Science, DOI: 10.1126/science.1150878). The semiconducting properties of these so-called graphene nanoribbons make them promising materials for electronics applications.
To create the graphene ribbons, Hongjie Dai and colleagues at Stanford University first chemically exfoliate graphite, loosening individual layers of graphene by giving the graphite a 60-second bath in 3% hydrogen in argon gas at 1,000 °C. They then "tear" the graphene into strips by sonicating the material in solution. Previously, scientists used lithographic patterning to cut graphene into ribbons. But Dai's chemical method yields narrower ribbons with far smoother edges.
