The Optical-drive Type Organic Field Effect Transistor for Driving the Electronic Paper
Abstract:Previously, by combining the organic field-effect-transistor (OFET) and the organic photoreceptor (organic photoconductor: OPC), an optical-drive type OFET was achieved. In this paper, in order to clarify the driving mechanism of this device, changes in channel current were evaluated after independently operating OPC part. As the results, the increase in the channel current at gate 0 V was observed, after the OPC independently operated by laser irradiation under applying gate voltage. Furthermore, utilizing the charge injection from gate electrode to OPC, the increase in the channel current was observed without laser irradiation. And, another device structure, in which the carrier generation layer (CGL) in OPC part was removed, was examined.
