From: Ultrabroadband, More than One Order Absorption Enhancement in Graphene with Plasmonic Light Trapping
Broadband absorption enhancement in graphene by plasmonic light trapping.
The solid red line shows the simulated spectra of absorption in the graphene for the structure in Fig. 1c. The absorption for the structures with just one type of crosses is described by the dashed blue line (large crosses) and dashed purple line (small crosses). The flat dashed line shows the absorption in a free standing graphene without enhancement.
