Field emission and lifetime characteristics of carbon nanotube paste including nitrogen foaming agent

Hee-Sung Moon; Jae-myung Kim; Seung-Joon Yoo

We added azodicarbamide (ADC) to protect carbon nanotube (CNT) paste from degradation. The agent produces nitrogen gas by heat at 190-210. Nitrogen (N/sub 2/) acts as the anti-oxidation gas for CNT. The measurement of field emission carried out using a diode structure showed that the electron emission of the agent-added CNT films uniformly had a field of 5.49 V//spl mu/m at a current density of 100 /spl mu/m/cm/sup 2/ (1/500 duty). Furthermore, the lifetime of CNT samples was about five times as much as that of the pristine ones.
