Abstract

PEDOT/PSS is an air-stable and solution-processable semiconductor polymer with great potential for electronic applications. In this research, we investigated the PEDOT/PSS-metal contacts using Al-PEDOT/PSS-Au as a test device. Abnormal electrical hysteresis phenomena were observed in both the current-voltage and capacitance-voltage characteristics of the device. A model in terms of metal-polymer interfacial MIS structure and ion motion in the polymer is proposed for explanation of the ‘hysteresis’ phenomena.
