摘要
We present the incorporation of periodic gold nanoparticle arrays into graphene-based photodetectors to enhance and tune light absorption of graphene. By the use of electromagnetic simulations, we show that light absorption in graphene can be manipulated by tuning plasmonic resonance. A maximum absorption of 30.3% with a full width of 135 nm at half maximum is achieved through systematic optimization of nanostructures.
