Zusammenfassung:By approaching the counter electrode to the carbon nanotubes (CNT) emitter, remarkable reduction of the cathode operating voltage has been accomplished in the under-gate CNT cathode structure. The peak emission current density of 2.5 mA/cm 2 , which is sufficient for high brightness CNT field emission display, was obtained at the cathode-to-gate voltage of 57 V when the CNT-to-counter electrode gap was 2.2 μm. The gate current was less than 10% of the anode current. The CNT cathode with low driving voltage can help the cost-effective field emission display implemented.
