Organic field-effect transistors (OFET) have gained significant interest for their potential in low-cost, large-scale, flexible, and printable electronic devices. However, they face numerous significant challenges, such as high operating voltage and leakage current. This study investigates the impact of using high-dielectric constant materials as gate dielectrics on the performance of OFETs. The goal is to improve OFETs by lowering the operating voltages using high gate dielectric organic and inorganic materials. …
