Abstract

An electrode for use in an organic optoelectronic device is provided. The electrode includes a thin film of single-wall carbon nanotubes. The film may be deposited on a substrate of the device by using an elastomeric stamp. The film may be enhanced by spin-coating a smoothing layer on the film and/or doping the film to enhance conductivity. Electrodes according to the present invention may have conductivities, transparencies, and other features comparable to other materials typically used as electrodes in optoelectronic devices.
