ACOUSTIC LOCAL MODE AND TA BAND MODE VIBRATION FOR THE MIXED CRYSTALS Cd1-xMnxTe
-
Abstract
We report here the acoustic local mode and TA band mode for the lattice vibration of the mixed crystals Cd1-xMnxTe as observed by very far infrared spectra. The occurence of the acoustic local mode and the weakly optical activity of TA mode induced by crystalline-mixing are discussed in light of the defect lattice dynamics.
