摘要: Light absorption of suspended monolayer graphene in the ultraviolet range is relatively low, which impedes potential applications for graphene-based optoelectronic devices. To enhance light-matter interaction a wide spectral range, we propose two plasmonic structures based on metal-dielectric-metal configuration. After rigorous optimization geometric parameters, broadband and enhanced light can be achieved. The bandwidth above 30% rate reach up to 245 nm (from 240 nm 485 nm), while relative 68%. optimal peak as high 54%. Besides, spectrum tuned by adjusting parameters. Physical insight revealed with electric magnetic field distributions. Furthermore, tolerance incident angle demonstrated, dependence polarization discussed. Our approach shows promising novel range.Light u...
