Figure 4. (A and B) The computed band structures; (C and D) PDOS; and (C1 and D1) extracted PDOS (-4 to 4); and (E and F) electron density difference of Mg₂ZnSb₂ and Ag- Mg₂ZnSb₂ systems. The yellow and red area denotes the loss and gain of electrons. The electron densities of the doped material were taken from -4.12 × 10^-4 e/Å. PDOS: Projected density of states.
