Nanoribbons Create On/Off Switch for Graphene

A new way to grow narrow ribbons of graphene, a lightweight and strong structure of single-atom-thick carbon atoms linked into hexagons, may address a shortcoming that has prevented the material from achieving its full potential in electronic applications. Graphene nanoribbons, mere billionths of a meter wide, exhibit different electronic properties than two-dimensional sheets of the

Oak Ridge National Laboratory Technology Writes Nanoscale Features in Metal Ink

Scientists at the Department of Energy”s Oak Ridge National Laboratory are the first to harness a scanning transmission electron microscope (STEM) to directly write tiny patterns in metallic “ink,” forming features in liquid that are finer than half the width of a human hair. The automated process is controlled y weaving a STEM instrument”s electron
