Figure 6
Calculated EELS and optical absorption α for (a), (b) MoS2-2H, (c), (d) MoS2-1L and (e), (f) MoS2-2L (ɛ2). Red and blue lines refer to the on-plane (xx, E c) and out-of-plane (xx, E || c) electric field oscillations, respectively. Experimental data from Beal & Hughes (1979) are shown for direct comparison. The green dashed boxes in panels (b), (d) and (f) show the part of the absorption spectrum in the visible region, which is reported in the upper right inset. |
