摘要：

Enhanced field emission from ZnO nanowires grown on carbon cloth (see Figure) has been measured. These emitters produced a field emission current density of 1 mA cm(-2) at about 0.7 V mum(-1) corresponding to an exceptionally high field-enhancement factor of 4.11 x 10(4). Such an extremely high field-enhancement factor is believed to be the combined effect of the high aspect ratio of ZnO nanowires and the geometry of the carbon-cloth substrate.
