摘要：

Field emission characteristics of single-walled carbon nanotube layers have been investigated at room and low temperatures. For these layers the emission current density of 10mA/cm(2) was obtained at the average field E-av = 1.6-3.8 V/mum. Current-voltage characteristics in Fowler-Nordheim coordinates have a break at emission current about 10(-8) A. Cooling of samples only insignificantly changed the form of current-voltage characteristics. This indicates, that investigated single-walled nanotubes have the metal type conductivity.
