Abstract
We investigated the pH effect on the carrier transport in conducting polymer PEDOT:PSS films by the combination of terahertz and infrared-ultraviolet spectroscopy, which revealed that the increase of the pH decreased the DC conductivity resulting from the decrease of carrier density and mobility due to the weak carrier localization.
