✦ Synopsis

Abstract

The back cover shows results from ab initio studies of a diluted magnetic semiconductor system by S. K. Nayak et al. (p. 1839). Depicted is the electronic density of states of Co‐doped ZnO (Zn~1–x~Co~x~O, x = 0.125), corrected by adding Hubbard‐like correlations to the Zn‐d and Co‐d orbitals with 7.5 eV and 5.0 eV, respectively. The additional incorporation of Hubbard‐like correlations into the electronic structure of ZnO improves the description of orbital hybridization by shifting the bands to correct locations below the Fermi energy. The experimental peak position of the Co 3d‐states at –3 eV and –7 eV, as obtained from valence‐band ultraviolet photoemission measurements available in the literature, thus agree with the corresponding spectral weight obtained in the calculations.
