Digital Design and Simulation of a Graphene Nanoribbon (GNR) Detector for Mid-Infrared (MIR) Radiation Detection

Abstract

Graphene nanoribbon detectors (GNR) are distinguished by the ability to engineer their energy bandgap, enabling the fabrication of semiconductor devices with different bandgaps that can operate in the FIR and THZ frequency ranges. Moreover, they are less sensitive to temperature variations compared to conventional detectors, which allows them to operate without the need for extensive cooling. In this paper, using mathematical modeling and numerical programming, we performed a numerical design to evaluate the performance of a graphene nanoribbon based photodetector operating in the Mid-infrared region (MIR), and we compare its thermal sensitivity with that of a quantm dot detector.
