Recent advancements in wearable and flexible electronic devices have increased the demand for lightweight andmechanically flexible organic field-effect transistors (OFETs). OFETs offer key advantages over conventional inorganic counterparts,including low-temperature processing, cost-effectiveness, and mechanical conformability. Among the various types of OFETs, ambipolarOFETs are particularly promising because they can reduce the number of fabrication steps and associated costs. These devicestransport both electrons and holes within a single channel, which simplifies circuit design and enables complementary logic withfewer components. However, these devices still face challenges owing to the imbalance in electron and hole transport. This imbalanceoften leads to asymmetric electrical characteristics and reduced overall performance, which limit the practical application of ambipolarOFETs in integrated circuits. Overcoming this issue requires careful material selection, interface engineering, and device architectureoptimization. This review highlights the significance of ambipolar OFETs, discusses their fabrication methods, and outlinesstrategies by which to improve ambipolar performance.
