Abstract :
The fabrication of carbon nano-tube (CNT) emitters with excellent field emission properties is described. CNT clusters synthesized by arc discharge were crushed, mixed with conductive pastes and then screen-printed. In order to obtain efficient field emissions, the mechanical surface treatment was applied to the printed CNT films. The measurements carried out using a diode structure reveal that the electron emission of the surface-treated CNT films uniformly turned-on with a field as low as about 1.0 V//spl mu/m. The emission current density was about 5 mA/cm/sup 2/ at a field of 4 V//spl mu/m. The vacuum packaged panel without an evacuation tube showed a stable emission image with a high brightness.
