我们提出了一种基于石墨烯-二硫化钼混合结构的新型生物传感器结构，采用低折射率的MgF2棱镜，以提高灵敏度和优点系数（FOM）。通过调节结构参数，比较选择不同的缺席层材料，可以获得灵敏度和FOM值分别高达540.8度/RIU和145度/RIU的超灵敏传感器。该结构适用于表面等离子体共振生物传感器集成器件的实现。(C) 2018年美国光学学会。
We propose, to the best of our knowledge, a new configuration of a biosensor based on the graphene-MoS2 hybrid structure by adopting the lower refractive index MgF2 prism in order to improve the sensitivity and the figure of merit (FOM). We can obtain an ultrasensitive sensor with values of sensitivity and FOM as high as 540.8 degrees/RIU and 145/RIU, respectively, by modulating the parameters in the configuration and comparatively choosing a different absentee layer material. The proposed structure is applicable in the realization of an integrated device for the surface plasmon resonance biosensor. (C) 2018 Optical Society of America.
