AbstractIn this study, we detailed our design for making a photoactive semiconductor/dielectric interface in order to study charge dynamics at the interface in combination with photoexcitation, using organic thin-film transistors (OTFTs) as local probes. The photoactive semiconductor/dielectric interface is formed from a hybrid gate dielectric (polymethyl methacrylate (PMMA) and titanium oxide (TiO(2))). Because the photogenerated electrons from TiO(2) nanoparticles under UV illumination can serve as the trapping centers for quenching hole carriers, p-type semiconductors showed the decrease of the hole mobility. Interestingly, n-type semiconductors displayed symmetric, opposing photoswitching effects at the same condition, showing that the photogenerated holes can function as a local positive gate voltage for improving the electron mobility. On the basis of this understanding, a remarkable example of mirror-image photoswitching effects in a single ambipolar OTFT was realized. These results may offer grounds for the creation of the future practical/multifunctional organic optoelectronic devices.
