Abstract

We review the results of a number of recent synchrotron radiation photoemission studies of the electronic structure of concentrated ternary semimagnetic semiconducting alloys. The materials examined include Cd1−xMnxS, Cd1−xMnxSe, Cd1−xMnxTe , Zn1−xMnxSe, and the narrow-gap Hg1−xMnxTe, Hg1−xMnxSe, and Hg1−xFexSe. Photon-energy-dependent photoemission methods are being used to probe the elemental and orbital contribution to the valence states. The new information is stimulating novel theoretical work on the electronic structure and lattice stability of these semiconductors.
