A sheet of diamond with crystals less than 5 nanometres across has conducted electrons for the first time, researchers from Argonne National Labs in Illinois told the ACS. This is because the film is so thin you can dope it with nitrogen. And as diamond already conducts “holes”—vacancies where electrons once were—it might be possible to use both of these properties to build diamond-based transistors. Combined with its hardness, this new-found property could be useful in building micromachines. The team made the films by breaking apart buckyballs (C60) or methane and letting the fragments condense. “Diamond will be a breakthrough technology,
