Nature Communications, Published online: 21 April 2026; doi:10.1038/s41467-026-71814-0 Multi-valued logic (MVL) devices hold promise to reduce the footprint and energy consumption of future electronic circuits. Here, the authors report the realization of zero differential transconductance plateau transistors based on 2D materials/CoFe2O4 heterojunctions, showing their application for MVL devices.
