The 3d transition metal ions (TMI) substituting for the cations in the tetrahedrally coordinated zincblende II-VI semiconductors display a localized mode above the rest-strahlen when introduced in dilute concentrations. The local mode observed in the infrared exhibits a characteristic dependence on the isotopic mass of the TMI. In the wurtzite II-VIs, the local mode undergoes a splitting into two components, one polarized along the optic axis and the other normal to it. The local mode frequency shows a striking non-monotonic dependence on the number of 3d electrons of the TMI.

Abstract

The 3d transition metal ions (TMI) substituting for the cations in the tetrahedrally coordinated zincblende II-VI semiconductors display a localized mode above the rest-strahlen when introduced in dilute concentrations. The local mode observed in the infrared exhibits a characteristic dependence on the isotopic mass of the TMI. In the wurtzite II-VIs, the local mode undergoes a splitting into two components, one polarized along the optic axis and the other normal to it. The local mode frequency shows a striking non-monotonic dependence on the number of 3d electrons of the TMI.
