Nanotubes as chemical reactor for nanoribbon production
August 10, 2011
Chemical reactions involving carbon and sulfur atoms held within a carbon nanotube lead to the formation of atomically thin strips of carbon (graphene nanoribbon) decorated with sulfur atoms around the edge.
The team has also discovered that nanoribbons — far from being simple flat and linear structures — possess an unprecedented helical twist that changes over time, giving scientists a way of controlling physical properties of the nanoribbon, such as electrical conductivity.
Devices based on nanoribbons could potentially be used as nano-switches, nano-actuators, and nano-transistors integrated in computers or data storage devices, the researchers said.
