Abstract
By using optical modulation spectroscopy, the electronic state and selective carrier accumulation processes in the channel region of unipolar and ambipolar organic field effect transistors (OFETs) were directly probed. The modulated spectra of unipolar single-layer pentacene and C60 OFETs corresponding well with their I–V characteristics were understood in terms of the injected carrier induced effect. On the other hand, for the double-layer C60/pentacene OFETs, it is indicated that the modulated spectra under both hole and electron accumulation cases generated mainly from the pentacene layer but with different characteristics, implying that the injected carriers accumulated at spatially separated locations.
