Abstract (in Japanese) (See Japanese page) 
(in English) Carrier injection and transport properties such as mobility, threshold voltage, and carrier injection voltage at source electrode were evaluated in p-type pentacene and n-type perylene derivative organic thin-film transistors (OTFTs) using displacement and channel current simultaneous measurements. From gate voltage frequencies of displacement current and channel current, in the case of pentacene thin-film transistors (TFTs) mobility, threshold voltage, and carrier injection voltage at source electrode showed no frequency dependences at frequencies between 1 and 50 kHz. On the other hand, in the case of PTCDI-C8 TFT, they showed frequency dependences from 10 Hz to 1 kHz; it was observed that threshold voltage shift due to bias stress, and that carrier injection process did not follow the gate voltage sweep.
