摘要：

An extremely low operating electric field has been achieved on zinc oxide (ZnO) nanowire field emitters grown on carbon cloth. Thermal vaporization and condensation was used to grow the nanowires from a mixture source of ZnO and graphite powders in a tube furnace. An emission current density of 1 mA/cm(2) was obtained at an operating electric field of 0.7 V/mum. Such low field results from an extremely high field enhancement factor of 4.11 x 10(4) due to a combined effect of the high intrinsic aspect ratio of ZnO nanowires and the woven geometry of carbon cloth.
