Sweden's Chalmers University researchers demonstrated a graphene-based transistor design that allows more compact RF mixer processing. This could very well be a breakthrough, because it not only allows designing much more compact radio-frequency electronics, but also allows circuits to run faster. This could accelerate the development of Terahertz electronics systems whose applications include radar, radio astronomy, and process monitoring. Its developers have named it G-FET, or Graphene field-effect transistor. An allotrope of carbon, graphene is an honeycomb lattice of carbon atoms on an atomic-scale. It is electrically-symmetrical, giving it the ability to act as electron or hole carrier. This means that a single G-FET can act as an RF mixer without needing the feeding circuits used in current designs.
