From: Structural and electronic properties of Eu- and Pd-doped ZnO
Total and partial density of states of the ZnO:Pd systems. Representing (a) ZnO:PdZn, (b) the ZnO:PdI, (c) ZnO:PdZn + VO, (d) ZnO:PdZn + ZnI systems. The solid black lines and the blue-shaded areas represent the total and Pd's partial 4d states, respectively. For clarity, the Pd's d states are scaled by a factor of five. Also, energy is represented with respect to the Fermi level.
