Original Abstract Submitted
A light-receiving device includes graphene including a light-receiving part; major electrodes electrically connected with the graphene, the major electrodes including a source electrode and a drain electrode, the light-receiving part being positioned between the source electrode and the drain electrode; a gate electrode electrically connected with the light-receiving part of the graphene via capacitive coupling; a circuit part electrically connected with the major electrode and the gate electrode; and an ionic substance contacting the light-receiving part of the graphene. The ionic substance is one of an anion having an acid dissociation constant of not less than 3 or a cation having an acid dissociation constant of not more than 11.
