Abstract
An electromagnetic wave detector includes a semiconductor layer, a two-dimensional material layer, a first electrode portion, a second electrode portion, and a ferroelectric layer. Two-dimensional material layer is electrically connected to semiconductor layer. First electrode portion is electrically connected to two-dimensional material layer. Second electrode portion is electrically connected to two-dimensional material layer with semiconductor layer interposed therebetween. Ferroelectric layer is electrically connected to at least any one of first electrode portion, second electrode portion and semiconductor layer. Electromagnetic wave detector is configured such that an electric field generated from ferroelectric layer is shielded with respect to two-dimensional material layer. Alternatively, ferroelectric layer is arranged so as not to be overlapped with two-dimensional material layer in plan view.
