유리기판 위에 성장된 탄소나노튜브를 이용한 평판 램프의 전계방출 특성

Abstract

We fabricated the 1-inch diode type flat lamp using CNTs, which were grown directly on soda-lime glass substrate at 600 ～ 650 ℃ by thermal chemical vapor deposition(CVD) of acetylene gas. Turn-on field was about 2.8 V/㎛. We observed that uniform and high brightness had been obtained. The brightness of CNT flat lamp was measured up to about 14 k㏅/㎡ at 2000V in spacing of 500 ㎛. The results showed that the CNTs were very good emission source and suitable for application in the lamp.
