Abstract
The carbon nanotubes (CNTs) film was fabricated successfully on 5 cm Ã 5 cm borosilicate glass substrate by using capacitive coupled radio frequency plasma-enhanced infrared thermal chemical vapor deposition equipment (CC-RF-PE-IT-CVD). The substrate temperature was 580 °C. Inborn Fe(OH)3 sol was used as catalyst during the growth. Observation by scanning electron microscope indicated CNTs nearly uniformly distributed on the substrate. The measurement results of field emission characteristics at three stochastic-selective zones indicated that the turn-on field of electron emission for the sample was around 2.1 V μmâ1, and emission current density was larger than 400 μA cmâ2 at 6 V μmâ1. Similar effective work function and field enhancement factor for the three different zones exhibited that the sample possesses good emission uniformity. Therefore, the cathode is suitable for FEDs.
