Carbon nanotube thin films because of their unique optical and electronic properties coupled with the flexibility and easy patternability are promising candidates for application in low cost, large area flexible displays and optoelectronics. In this work, a novel printing device comprising a single-walled carbon nanotube (SWCNT) thin film and a molecularly doped polymer layer of arylamine is reported. Results show that hole injection from the SWCNT thin film to the arylamine layer occurs under the influence of an electric field. The efficiency of the hole injection process was found to be dependent of the surface conductivity of the SWCNT film and the strength of the electric field across the bilayer device. The use of this hole injection process to generate electrostatic latent images for novel digital printing application is discussed.
