A photodiode-based logic device employing scalable heterojunctions of carbon nanotubes and silicon whose output currents can be manipulated by both optical and electrical inputs is developed. Bidirectional phototransistors and novel clock-triggerable logic elements, such as a mixed optoelectronic AND gate, a 2-Bit optoelectronic ADDER/OR gate and a 4-Bit optoelectronic D/A converter, are also demonstrated.
