Abstract(in English) | Organic field effect transistors (OFETs) have attracted much attention in relation to the recent progress in organic electronics. In order to investigate a mechanism of doping to organic semiconductors, we investigated the influence of oxygen exposure to pentacene and poly (3-hexylthiophen)(P3HT) FET using displacement current measurement (DCM) and infrared absorption spectroscopy in the multiple internal reflection geometry (MIR-IRAS). The DCM results revealed that the oxygen doping effect is small in dark condition, but is much enphanced by light illumination (photo-induced doping). From MIR-IRAS, we conclude that the charge-transfer reaction is accelerated by the light illumination. |
