Graphene semiconductors developed

23 Nov 2012

Researchers at the Georgia Institute of Technology have developed a graphene semiconductor that could enable large area flexible electronics.

The graphene was formed into grooves to create a bandgapGraphene traditionally acts like a conductor, but scientists discovered that bending it produces a bandgap, allowing it to work as a semiconductor. Researchers grew two layers of graphine on a grooved silicon carbide base. The layers set into the grooves, allowing the material to form a bandgap and act as a semiconductor, reports the Overclockers club website.

The team are now studying how the size of the grooves affects the conductivity of the graphene, before working on further development.
