Dual?Gate Anti?Ambipolar Transistor with Van der Waals ReS ₂ /WSe ₂ Heterojunction for Reconfigurable Logic Operations

A dual-gate anti-ambipolar transistor (AAT) with a two-dimensional ReS2 and WSe2 heterojunction is developed. The characteristic ?-shaped transfer curves yielded by the bottom-gate voltage are effectively controlled top-gate voltage. This feature applied to logic operations, bottom- voltages acting as two input signals drain current (Id) monitored an output signal. Importantly, single AAT exhibits all two-input operations (AND, OR, XOR, NAND, NOR, XNOR) under optimized voltages. Additionally, (Vd)-induced switching between AND OR achieved. These features advantageous for simplifying circuit design.
