US11860033B2 Photodetector, photodetector array, and drive method comprising a second transistor including a channel of first conductivity type and a first transistor including a channel of second conductivity type that has polarity opposite to polarity of the first conductivity type 有权

Photodetector, photodetector array, and drive method comprising a second transistor including a channel of first conductivity type and a first transistor including a channel of second conductivity type that has polarity opposite to polarity of the first conductivity type
Abstract:
A photodetector includes: at least one avalanche photodiode including a first semiconductor layer of a first conductivity type and a second semiconductor layer of a second conductivity type; a first transistor connected to the first semiconductor layer and including a channel of the second conductivity type that has polarity opposite to polarity of the first conductivity type; and a second transistor connected to the first semiconductor layer and including a channel of the first conductivity type.
