Abstract
Electronic structures of ZnO-based dilute magnetic semiconductors (DMS) are investigated within the self-interaction-corrected local density approximation (SIC-LDA). These results are compared with those calculated within the standard LDA. The Korringa–Kohn–Rostoker method combined with coherent potential approximation has been used. We find the differences between LDA and SIC-LDA calculations, in the band-gap energy. The energetic position of the Zn 3d bands and the description of the transition-metal d bands, have been studied. In contrast to the standard LDA calculations, the results obtained within SIC-LDA are in good agreement with the experimental ones.
