Abstract
A graphene based detector device can include a source, a drain, and a gate. The gate can incorporate a discharging element and a graphene sheet that is proximate to the discharging element. The graphene sheet for the transistor can have a decreasing width, from a maximum width wdistal to the discharging element to a minimum width wproximate to the discharging element. An electric potential can be established across graphene sheet, to facilitate funneling of the electrons from the graphene sheet (which are caused by quanta of electromagnetic radiation) toward the discharging element. The devices can be formed in an array to establish an antenna that operates according to the quantum nature of light, as opposed to resonance (wavelength). Multiple graphene layers that are doped using different materials can be included. The multiple layer funnel electrons at specific frequencies, to create an operating frequency range for the device.
