Abstract: Photodetectors and methods of forming the same include a first electrode. A carbon nanotube film is formed on the first electrode. A first graphene sheet is formed on the carbon nanotube film. A second graphene sheet is configured to exert an electrical field on the first graphene sheet that changes an electrical property of the first graphene sheet.
