High-performance CNT(Carbon Nano Tube) emitter is developed for various field emission device applications. The emitter is formed from the CNT paste mixture consists of selected nanometal fillers, ethyl cellulose binder and terpineol solvent. Developed CNT emitter shows good surface morphology and operates stable high current density. And CNT emitter shows high-temperature endurability over 900C in the vacuum circumstance.
