  In this work the electronic properties of Fe doped CuO thin films are studied
by using a standard density functional theory. This approach is based on the
abinitio calculations under the Korringa Kohn Rostoker coherent potential
approximation. We carried out our investigations in the framework of the
general gradient approximation and self interaction corrected. The density of
states in the energy diagrams are presented and discussed. The computed
electronic properties of the studied compound confirm the half metalicity
nature of this material. In addition, the absorption spectra of the studied
compound within the Generalized Gradient Approximation, as proposed by Perdew
Burke Ernzerhof approximations are examined. When compared with the pure CuO,
the Fermi levels of doped structures are found to move to the higher energy
directions. To complete this study, the effect of Fe doping method in CuO has
transformed the material to half metallic one. We found a high wide impurity
band in two cases of approximations methods.
