Nanoribbons for graphene transistors for tomorrow's nanoelectronics

Scientists report how they have managed for the first time to grow graphene ribbons that are just a few nanometres wide using a simple surface-based chemical method. Graphene ribbons are considered to be hot candidates for future electronics applications as their properties can be adjusted through width and edge shape.

Carbon nanotubes as transistor material

ETH Zurich researchers have built a transistor whose crucial element is a carbon nano-tube, suspended between two contacts, with outstanding electronic properties. A novel fabrication approach allowed the scientists to construct a transistor with no gate hysteresis. This opens up new ways to manufacture nano-sensors and components that consume particularly little energy.
