Abstract
This electromagnetic wave detector that detects electromagnetic waves by performing photoelectric conversion includes: a substrate; an insulating layer that is provided on the substrate; a graphene layer that is provided on the insulating layer; a pair of electrodes, which are provided on the insulating layer, and which are connected to both ends of the graphene layer, respectively; and a contact layer that is provided such that the contact layer is in contact with the graphene layer. The contact layer is formed of a material having a polar group, and a charge is formed in the graphene layer by having the contact layer in contact with the graphene layer.
