Abstract
A MoS2-Graphene hybrid layer Based High Performance Refractive Index SPR Sensor is illustrated in this paper. Intended for the enhancement of sensor angular sensitivity (S), signal to noise ratio (SNR), quality factor (QF), first of all, the impact of gold layer thickness is investigated and optimized to 40 nm, after then the MoS2 and graphene coting layers are optimized to four (4) and three (3) layers, respectively. Further that, at this optimum structure, the minimum reflectance and SPR angle are decorated. It is seen that the angular sensitivity of the optimum assembly, improved to excellent value of 130 deg-RIU−1 with improved angular SNR of 1.37 and QF of 17.02 RIU−1. At the end of this paper, an analysis specifically for numerically DNA hybridization is considered.
