Tip of Atomic Force Microscope

Tip of an atomic force microscope

In a technique known as thermochemical nanolithography, the tip of an atomic force microscope uses heat to turn graphene oxide into reduced graphene oxide, a substance that can be used to produce nanocircuits and nanowires with controllable conductivity.

The technique, devised by researchers from the Georgia Institute of Technology, is a breakthrough toward creating nanocircuitry on graphene, widely regarded as the most promising candidate to replace silicon as the building block of transistors.
