Paper Abstract

In this work, the photoresponse and photo-induced memory effect were demonstrated in an organic field-effect transistor (OFET) with semiconductor pentacene and SiO2 as the active and gate dielectric layers, respectively. By inserting AlOX nanoparticles (NPs) at the interface of pentacene/SiO2, obvious enhancing photoresponse was obtained in the OFET with the maximum responsivity and photosensitivity of about 15 A/W and 100, respectively. Moreover, the stable photoinduced memory effect was achieved in the OFET, attributing to the photogenerated electrons captured by the interface traps of the AlOX NPs/SiO2.
