Body emission characteristics from lateral single‐walled carbon nanotube emitters

Abstract

The uniform body emission properties of lateral single-walled carbon nanotubes (SWNTs) emitters grown by chemical vapor deposition are reported. Lateral SWNTs lying on the substrate were found to possess a turn-on field of at least 1.67 V/µm and a field enhancement factor of 5223 at most. A flat panel display requiring 1 mA/cm 2 was carried out at 4.7 V/µm. The large area uniform luminescence was obtained due to the uniform electrical field intensities throughout the body of SWNTs according to a calculation of electrical field distribution. Good field emission characteristics with a simple process could be more applicable for display applications.
