«We have found that a cathode with highly crystalline single - walled carbon nanotubes and an anode with the improved phosphor screen in our diode structure obtained no flicker field emission current and good brightness homogeneity,» Shimoi said. (sciencedaily.com)
Field emission of electrons from individually mounted carbon nanotubes has been found to be dramatically enhanced when the nanotube tips are opened by laser evaporation or oxidative etching. (science.sciencemag.org)
