摘要

提出了一种基于克雷茨曼结构的高灵敏度表面等离子体共振生物传感器。本文提出了一种硅层外加二维过渡金属二硫化物(TMDC)和二硒化钨(WSe2)的六层生物传感器模型。灵敏度是表征生物传感器最重要的参数。结果表明，7层硅和1层WSe2的灵敏度最高，为237.5□RIU。

Highly Sensitive Surface Plasmon Resonance Biosensor Using WSe2 and Silicon

In this paper, highly sensitive surface plasmon resonance biosensor based on Kretschmann configuration is presented. Here we proposed six layer model of biosensor with silicon layer in addition with two dimensional transition metal dichalcogenide (TMDC) Tungsten Diselenide (WSe2). Sensitivity is the most important parameter to characterize a biosensor. It is observed that highest sensitivity 237.5 □RIU can be observed with seven layer of silicon and only one layer of WSe2.
