Growth of carbon nanotubes on the glass substrate for flat panel display applications

Abstract

We have grown carbon nanotubes (CNTs) on the soda-lime glass substrates using chemical vapor deposition of C,H, gas at 550degreesC. We used electro-plated Ni thin film as a catalyst and screen-printed Ag thick film as a cathode The turn-on field was about 2.55 V/mum with an emission current density of 10 muA/cm(2), and electric field was about 4,0 V/mum with an emission current density of 3 mA/cm(2) Fowler-Nordheim plot shows good linear fit, indicating that the emission current of CNTs follows the Fowler-Nordheim behavior. This process is suitable for mass production of CNT Field emission display(CNT-FED), because of its merits; low temperature (! 550 C) process, easiness of CNT patterning, non-vacuum process, large area uniformity.
