Graphene-based electronics ‘one step closer’
Scientists at the University of Manchester have shown that it is possible to create long, structurally well-defined ribbons of graphene.
In tests, the graphene nanoribbons (GNRs) exhibited excellent charge-carrier mobility and longitudinal extension, while preserving their high structural definition
It is hoped that this will enable their use in next generation transistors, something which has not previously been possible.
Lead researcher Dr Cinzia Casiraghi said: "The GNRs produced with this method can allow development of graphene-based transistors, but they can also be used as active material in solar cells, chemical sensors and as novel energy storage materials.
"Because of the potential uses of this material, Raman spectroscopy is expected to play a crucial role in determining the optical and electronic properties of the ribbons."
