The renormalization of nodal quasiparticles is evaluated in terms of mass enhancement spectra.
The real and imaginary parts of mass enhancement spectra were directly deduced from the APRES data shown in Figure4[7].
Figure 11 shows the maximum near-field enhancement spectra of NC-MNS, NC-DNS, MNS-NG and DNS-NG nanostructures.
Figure 4(a) shows the absorption enhancement spectra of AS arrays with different NP size (diameter: 20, 30, and 40 nm), obtained by the FEM simulations.

However, the mass enhancement spectra in Figure5a,b,d are suggestive of the presence of multiple components in the intermediate-energy range.

From the enhancement spectra as shown in Fig. 3c, d, one sees that, at the wavelength range shorter than 600 nm, there is a broad enhancement bump with multiple peaks taking place.
Though the absorption enhancement spectra of the two different optimal devices are similar as well, the mechanisms of light trapping at the corresponding enhancement peaks are distinct from each other.
In the present work, we propose and demonstrate a simple numerical simulation scheme for obtaining photocurrent enhancement spectra of plasmonic solar cells, which enables obtaining instant results for the entire sunlight spectrum, for providing future directions for device improvement.
