Figure 8.

Total κ = κ_el + κ_l (a,c) and the dimensional figure of merit ZT (b,d) versus charge concentration for electron‐doped MAPbI₃, calculated at two different temperatures; κ_l is extrapolated from the experimental data published elsewhere. Black dots and red squares correspond to the experimental κ_l values for single crystal MAPbI₃ and poly crystal MAPbI₃, respectively; the other symbols are for rescaled κ_l values (indicated in the legend), mimicking eventual κ suppression occurring in 2D wells of thickness L = 40 nm (green diamonds), 20 nm (blue circles), and 10 nm (orange squares).
