Room-Temperature Amplification of Terahertz Radiation by Grating-Gate Graphene Structures
We study terahertz (THz) radiation transmission through grating-gate graphene-based nanostructures. We report on room-temperature THz radiation amplification stimulated by current-driven plasmon excitation. Specifically, with an increase of the dc current under periodic charge density modulation, we...
