A MoS 2 -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 MoS 2 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.

基于混合结构的高性能 SPR 传感器：DNA 杂交结构优化的数值方法

本文介绍了一种基于 MoS 2 -石墨烯混合层的高性能折射率 SPR 传感器。旨在提高传感器角灵敏度 (S)、信噪比 (SNR)、品质因数 (QF)，首先研究金层厚度的影响并优化至 40 nm，然后是 MoS 2 和石墨烯涂层分别优化为四 (4) 层和三 (3) 层。此外，在这种最佳结构下，最小反射率和 SPR 角被装饰。可以看出，最佳组件的角度灵敏度提高到 130 deg-RIU -1 的优异值，同时提高了 1.37 的角度 SNR 和 17.02 RIU -1 的 QF。在本文的最后，考虑了专门针对数值 DNA 杂交的分析。
