Analysis of infrared spectra with narrow band absorption by a graphene/square-ring structure

A graphene covered on square-ring structure is designed and fabricated to achieve narrow band absorption of three peaks in the infrared band. The absorption rates of graphene/square-ring structures calculated by simulation are 90.49%, 65.67% and 20.38%, respectively, and the experimentally measured...

Summary:A graphene covered on square-ring structure is designed and fabricated to achieve narrow band absorption of three peaks in the infrared band. The absorption rates of graphene/square-ring structures calculated by simulation are 90.49%, 65.67% and 20.38%, respectively, and the experimentally measured absorption rates are 82.12 %, 53.13 %, and 16.58 %, respectively. Comparing the absorption rate of simulation calculation with experimental measurement, as well as the reasons for the differences are presented. The dynamic control characteristics of the graphene device are not observed with this structure in the experiment, which is different from the simulation. We analyzed the reason for this distinction and proposed three solutions based on the experimental design. The research results of this paper provide an important reference to the design and preparation of graphene devices.
