Array sensor

Abstract

The array sensor of the present invention comprises a plurality of detection regions arranged in one-dimensional or two-dimensional order. Each detection region has a plurality of sub-regions. Each of the plurality of sub-regions has a light-receiving element, which includes a gate electrode, a source electrode, a drain electrode, and a photoelectric conversion unit. The photoelectric conversion unit contains a two-dimensional layered material electrically connected to the source electrode and the drain electrode. In the light-receiving element, current flows between the source electrode and the drain electrode according to the magnitude of the voltage applied to the gate electrode and the intensity of the light incident on the photoelectric conversion unit. The plurality of sub-regions have different time response characteristics. In each detection region, the signals from the plurality of sub-regions are synthesized and output as an output signal.
