Photo-Controlled Quantum Capacitors in Gated Graphene-Insulator-Graphene for Terahertz Frequency and Phase Modulations
IEEE Journal of the Electron Devices Society(2020)
摘要
This paper proposes a theoretical model of photo-controlled quantum capacitors in double-gated graphene-insulator-graphene (DGGIG) structure for terahertz (THz) frequency and phase modulations. In the model, the current-voltage characteristics of each segment of the DGGIG structure are controlled by different gate voltages. Using the different voltages, the DGGIG structure can be used to either ge...
