Carbon nanotubes (CNTs) have attracted much attention as electron emitters for field emission displays (FEDs) due to a combination of reasons including their extremely small diameters, chemical and mechanical stability, and good current carrying capacity. The longest vertically aligned CNTs with the smallest diameters, hence the largest electric field enhancement factor, are the most ideally suited for electron emission. Colour FED prototypes based on CNT emitters, previously reported have been working in the diode mode. Triode mode FEDs are needed to satisfy the requirements of the market in terms of power consumption, brightness, lifetime, colour, and cost. Plasma enhanced chemical vapour deposition (PECVD) is a controllable and deterministic method for growing vertically well-aligned carbon nanotubes (VACNTs). 1-3 The ability to control the location, orientation, and dimension of the nanotubes is essential for their use in triode structures especially screen sizes up to 15 inches where high resolution is needed. Although controlled growth of CNTs using PECVD has shown very promising results, the challenge is to use this technology to grow well-aligned CNTs on large areas suitable for gating in a triode display.
