Description
Chungryeol Lee and colleagues build a transistor with three stable states in 2026, driven by light. Most switches hold just on and off, which wastes room in dense circuits. A layered junction plus a tuned entry barrier gives this device a middle state that light can set.
The middle state can be dialed while the device draws almost no idle power. A full ternary inverter built from it swings both ways as logic demands. Three inverter flavors fit in a single device by light choice alone. A pixel circuit sorts and merges image parts as a proof of use. Three value logic gets a compact part.
