Figure 2(a) shows the images of the bulk TNM structure, the TNM structure without monolayer MoS2 (structure I), and the monolayer MoS2 structure without Ag nanorods (structure II) under TM polarized normal illumination (magnetic field along the y-axis). absorption spectrum. It can be seen from Figure 2(a) that the absorption rate of the TNM structure is higher than 95% in the range of 400-504nm and 519-637nm; the average absorption rate in the range of 400-700nm reaches 97%, which is effective through the plasma near-field concentration effect Confine the incident light to promote the absorption of MoS2.

Figure 2 (a) shows the absorption spectra of the overall TNM structure under TM polarized normal illumination (magnetic field along the y-axis), the TNM structure without monolayer MoS2 (structure I), and the monolayer MoS2 structure without Ag nanorods (structure II). From Figure 2 (a), it can be seen that the absorption rate of TNM structure is higher than 95% in the range of 400-504nm and 519-637nm; The average absorption rate reaches 97% in the range of 400-700nm, effectively limiting the incident light and promoting the absorption of MoS2 through the plasma near-field concentration effect.

Fig. 2(a) shows the absorption spectra of the whole TNM structure (magnetic field along the Y axis), the TNM structure without single-layer MoS2 (structure I) and the single-layer MoS2 structure without Ag nanorods (structure II) under normal illumination with TM polarization. As can be seen from Figure 2(a), the absorption rate of TNM structure is higher than 95% in the range of 400-504nm and 519-637nm; In the range of 400-700nm, the average absorption rate reaches ninety-seven percent, which effectively limits the incident light and promotes the absorption of MoS2 through the plasma near-field concentration effect.
