Figure 2. Ionic and electronic contributions (εp, εe) to the dielectric function ε(ω) of MAPbI3.

Figure 2

The top/bottom figure shows the real/imaginary part of ε(ω). The solid red/dashed blue line are, respectively the results from the DFPT(T = 0 K)/MD(T = 300 K) method. The inset shows a zoom-in of Reεp(ω) close to the Exb of 45 meV.
