  • Researchers peer into nanowires to measure dopant properties —  EurekAlert! - Breaking News
  • The amount of dopant determines the conductivity of the nanowire. —  EurekAlert! - Breaking News
  • But because nanowires are so small - with diameters ranging from 3 to 100 nanometers - researchers have never been able to see just exactly how much of the dopant gets into the nanowire during synthesis. —  EurekAlert! - Breaking News
  • By precisely measuring the amount of dopant in a nanowire, researchers can finally understand the synthesis process on a quantitative level and better predict the electronic properties of nanowire devices. —  EurekAlert! - Breaking News
  • "We simply mapped where all the atoms were in a single nanowire, and from the map we determined where the dopant atoms were," he says. —  EurekAlert! - Breaking News
