This letter reports on flexible field emitter arrays of single-walled carbon nanotubes (SWNTs) aligned on organic polymer substrates. An array of gold electrodes was patterned on the Ti-coated polymer substrate by sputtering gold through a shadow mask. A self-assembly monolayer of organic molecules was then formed on the gold electrodes using thiol chemistry. Cut SWNTs prepared by acidic treatment were attached to the end of the organic molecules. The field emission measurement showed that the turn-on field was 3.88 V/mum at the emission current density of 10 muA/cm(2). The current density was 1.6 mA/cm(2) at 6 V/mum. This room temperature process is suitable for the fabrication of flexible electronic devices with carbon nanotubes. (C) 2003 American Institute of Physics.
