Effect of Cr substitution on the electronic structure of CuAl1-xCrxO2

The geometries and electronic structures of CuAl1-x Crx O2 have been investigated using density-functional theory with on-site corrections for strongly correlated systems (GGA+U) for x=0, 1 2, 1. Al is found to be well described within the ionic model, with a valence charge corresponding to a +3 oxi...
