Adding function to graphene nano-ribbons through this process could make possible the sought-after goal of atomic-scale components made of the same material, but with different electrical behaviors
Using graphene ribbons of unimaginably small widths – just several atoms across – a group of researchers at the University of Wisconsin-Milwaukee (UWM) has found a novel way to “tune” the wonder material, causing the extremely efficient conductor of electricity to act as a semiconductor.
In principle, their method for producing these narrow ribbons – roughly equal to the diameter of a strand of human DNA – and manipulating the ribbons’ electrical conductivity could be used to produce nano-devices.
Graphene, a one-atom-thick sheet of carbon atoms, is touted for its high potential to yield devices at nanoscale and deliver computing at quantum speed. But before it can be applied to nanotechnology, researchers must first find an easy method of controlling the flow of electrons in order to devise even a simple on-off switch.
