A novel all-plastic diode based upon pure polyaniline material

All-plastic electronic devices have developed increasingly nowadays and a trend to use them replacing the conventionally Si-based inorganic semiconductor devices is becoming attractive. Here, we developed a new and simple method to fabricate a single-component all-polymer diode based on a conducting polymer, polyaniline (PANI), using different manners to form films on two ends of a transparency with an obviously divided boundary between them. The different doping degree is considered to induce this rectification.
