Simulation study of tungsten disulfide nanosheets -Au fiber surface plasmon resonance sensor

Tungsten disulfide (WS2) nanosheets is a promising two-dimension (2D) material for offering lots opportunities in the development of new biological and chemical sensors and sensing strategies. Fiber SPR sensor is a powerful tool in the field of biology and chemistry. In this work, we simulated the effect of different tickness WS2 nanosheets on the fiber SPR sensor. The result show that, the SPR sensor perform best when WS2 nanosheets is 9.6 nm. Its refractive index sensitivity is 2018.4nm/RIU, the full width at half maximum is 151.4 nm, and the quality factor is 1.333.
