## Description

- description: We demonstrate that the gate voltage Vg tunes the Schottky photocurrent
    ISG for the irradiation of two lights (Light A and B) in an n-AlGaAs/GaAs/AlGaAs
    double-heterojunction. Light A is a 975-nm-laser that illuminates the entire Schottky
    gate region at 280μW/mm2. Light B is a 670-nm-laser that locally illuminates the
    ungated region at 0.4μW. When Vg = 0V, Light B doubles ISG for Light A. At Vg
    = 87mV, ISG is generated only when both Light A and B are irradiated simultaneously,
    like the logical operation A∩B. When Vg = 165mV, ISG is induced only for the illumination
    of Light A alone, like A∩B ̅.
