Investigating versatile capabilities of organic field-effect transistors incorporated with vacuum-deposited metal nanoparticles

Abstract

Despite the promise of organic field effect transistor-based non-destructive readout devices and circuit development, the challenges in bias stress-induced charge trapping for stable operation still persist. This study introduces optically programmable organic field-effect transistors based on metal nanoparticles' plasmonic effects. Noble metal nanoparticles vacuum-deposited on an organic semiconductor layer not only enhance photon absorption and photocarrier generation but also function as charge trapping centers, thereby, modulating charge retention characteristics. According to the proposed mechanism on optical programming, we expect that the proposed device architecture may contribute to development of advanced information technology devices. Optically programmable organic field-effect transistors, developed using vacuum-deposited metal nanoparticles, enhance photocarrier generation and act as charge trapping centers, modulating charge retention.
