Abstract (english)
The propagator of the induced dynamically screened Coulomb interaction W ind (Q, ω, z, z ) is calculated for the MoS2 monolayer. The energy-loss rate of a point charge placed near the MoS2 monolayer is calculated (using the spatial resolution of the W ind in the direction perpendicular to the MoS2 plane) and successfully compared with very recent electron-energy-loss spectroscopy measurements of Hong et al. [J. Hong et al., Phys. Rev. B 93, 075440 (2016)]. The induced propagator W ind , compared with its classical analogous propagator, is used to determine the effective dielectric function eff (ω) of atomically thick crystals. It is shown that eff (ω) extracted from W ind is in good agreement with the dielectric function of the MoS2 extracted from the ellipsometry measurements. A recently proposed method for calculation of the dielectric tensor in quasi-two-dimensional crystals is used to calculate the parallel (ω) and perpendicular ⊥ (ω) dielectric functions in MoS2 , which are compared with some previous measurements and calculations.
