摘要
Extensive density functional theory investigations have been made on the spatial distribution of Cr atoms and associated magnetism of zinc-blende Cr:AlAs. The calculated results show that embedded Cr clusters, formed on the substitutional Al and interstitial sites, can lead to great changes in the local structure and magnetism of Cr:AlAs, which is very different from that assumed by the usual homogeneous model.
