New graphene-based electronics could take a page out of the silicon electronics book
An organic molecule that has been found to be effective in making silicon-based electronics may be viable for building electronics on sheets of carbon only a single molecule thick. Researchers at the Max Plank Institute for Metals Research in Stuttgart report the advance in a paper appearing online in the journal Physical Review B on June 1.
In a Viewpoint article in the current issue of APS Physics, Alexei Fedorov of the Lawrence Berkeley National Laboratory describes the challenges of creating electronic devices built of graphene and recent attempts to identify doping materials to do the job.
