Analysis and Simulation of the Optical Properties of a Quantum Dot on a Graphene Nanoribbon System

In this work, we theoretically study the optical properties of a graphene nanoribbon with quantum dot (QD) on it. The system consists dimensions 400 × 3100 (nm2) and nanoscale radius. is symmetrically located at center to simplify mathematical model. To calculate (susceptibility) system, broadband electromagnetic wave (0.5–2.5 μm) applied structure model dipole-dipole interaction. Considering input field calculating total induced polarization, susceptibility calculated. excites surface plasmon excitons QDs. dipoles in QD will interact each other. We show that parameters both materials strongly influence particular, effect QDs (location radius) considered was studied. obtained results can be used introduce periodic structures by inserting array nanoribbon. Additionally, applications such as reflectors, couplers, wavelength filters designed. presented theoretical framework, describe all optoelectronic optomechanical complex systems.
