Abstract

Large area (3×3mm2) infrared detectors which present a fast rise of their output upon pulsed excitation can be made by using PEDOT/PSS with a low surface resistance. Thus, the action of the infrared sensitive device is based on a change in resistance after photo-excitation of charge carriers in PEDOT/PS via their low-energy absorption features. The absence of any measurable delay in the response of the device is consistent with the view that the charges on the polymer chain are responsible for the absorption of infrared radiation.
