| Summary: | In this study, we present a reconfigurable feedback field-effect transistor (FET) that can operate in both p- and n-type configurations using a feedback mechanism. In contrast to previously reported reconfigurable FETs, our device utilizes a single gate to trigger a feedback mechanism at the center, resulting in steep switching characteristics. The device exhibited high symmetry of transfer characteristics, an on/off current ratio of approximately 10<sup>10</sup>, extremely low subthreshold swings, and a high on-current of approximately 1.5 mA at low gate voltages in both configurations. In addition, because of their hysteresis and bistable characteristics, they can be applied to various electronic devices. These characteristics were analyzed using a commercial device simulator.
