Electromagnetic wave detector and electromagnetic wave detector array

Abstract

An electromagnetic wave detector includes a first photosensitizing layer, a first electrode portion, a first insulating layer, a two-dimensional material layer, a second electrode portion, and a second photosensitizing layer. The first insulating layer is provided on the first photosensitizing layer. The two-dimensional material layer is provided on the first insulating layer. The two-dimensional material layer is electrically connected to the first photosensitizing layer. The first photosensitizing layer is connected to the two-dimensional material layer. The second photosensitizing layer has an absorption maximum value in a wavelength range different from that of the first photosensitizing layer. The second photosensitizing layer causes a voltage change in the wavelength range different from that of the first photosensitizing layer. The first insulating layer is disposed between the first photosensitizing layer and the two-dimensional material layer.
