چکیده
|
In this paper, a surface plasmon resonance (spr) sensor based on the hybrid structure of silver (ag)-indium tin oxide (ito)-graphene is proposed and investigated. spr biosensors are subdivided into three kinds of structures ag, ag-graphene, and ag-ito-graphene, when carried out using their respective optimized structure parameters. according to our analysis and comparison, the ito-assisted spr biosensor has an optimal reflectivity of 3.587 × 10−8 and a maximum phase sensitivity of 1.707 × 106°/riu, which shows that ito can be employed to further enhance the spr sensing performance even with the existence of graphene.
