    • This assumption is not strictly true. TEM images show that the nanoparticles can have a few "corners," although for practical purposes, neglect of corners and the hierarchy of length scales in these MoS2 nanoparticles is a reasonable assumption.

    • Based on our assumption that the interlayer polarizability of IF is the same as 2H, ε A2u (∞) =6.2 for IF. Then using Eq. 4 and fitting result ε̄ (∞) =5.6 of IF, we got ε E1u (∞) =8.3, which were shown in Table 1.
