Abstract
Multi-valued logic (MVL) can improve information density and reduce circuit complexity, but reliable implementation requires stable intermediate logic states. In this presentation, we demonstrate a single-polymer organic electrochemical transistor that exhibits a robust zero-differential transconductance (ZDT) state, enabling reliable ternary logic operation. A ternary inverter constructed from the device shows three well-defined logic levels, balanced voltage gain, and stable dynamic switching behavior. Spectroscopic and structural analyses reveal that the intermediate state originates from a transition between surface electrostatic gating and bulk electrochemical doping. Hardware-aware neural-network simulations further demonstrate the benefits of ternary operation, achieving 89% MNIST classification accuracy compared with 74% for binary networks. These results establish a simple route toward single-semiconductor multi-valued logic and low-power neuromorphic hardware.
