Abstract
An electromagnetic wave detector includes a light-receiving element, an insulating film, a two-dimensional material layer, a first electrode part, and a second electrode part. The light-receiving element includes a first semiconductor portion of a first conductivity type and a second semiconductor portion. The second semiconductor portion is joined to the first semiconductor portion. The second semiconductor portion is of a second conductivity type. The insulating film is disposed on the light-receiving element. The insulating film has an opening portion. The two-dimensional material layer is electrically connected to the first semiconductor portion in the opening portion. The two-dimensional material layer extends from on the opening portion onto the insulating film. The first electrode part is disposed on the insulating film. The first electrode part is electrically connected to the two-dimensional material layer. The second electrode part is electrically connected to the second semiconductor portion.
