Polyethylenedioxythiophene (PEDOT) and its polymer complexes have been widely studied as transparent electrodes and charge transporting buffer layers in various optoelectronic devices. Chemical treatment on a stock solution or thin films of PEDOT composites have shown to affect the doping level, electrical conductivity, and work function of the films. In this work, we chemically controlled doping levels of the PEDOT films and investigated their morphological features by using atomic force microscopy and grazing-incident X-ray diffraction. We found that chemical dedoping process altered the crystalline structures of PEDOT films. To gain a deeper insight of the processing-property relationship, we also studied their electronic transitions and charge-transport properties. The changes in the morphology upon doping control, along with those in the charge carrier densities, resulted in optical and electrical properties of their films. |
