Detectors of terahertz and infrared radiation based on p-i-n graphene structures utilizing interband transitions are proposed and evaluated. Using the developed device model, the detector responsivity and detectivity is calculated as functions of the number of graphene layers, energy of photons, bias voltage, and temperature.
It is demonstrated that the proposed detectors can substantially surpass in the terahertz and middle infrared spectral ranges quantum-well and quantum-dot detectors as well as detectors based on narrow-gap and gapless bulk semiconductors |
