Abstract:

Field exciton-vibration spectroscopy of the ZnTe : Ni semiconductor has revealed a local lattice vibrational mode due to the nickel impurity, which is negatively charged relative to the lattice. The electroabsorption spectrum of ZnTe : Ni contains equidistant vibrational replicas of the zero-phonon line of frequency 13 +/- 1 THz, which exceeds the limiting phonon frequency in ZnTe by more than twofold. Possible reasons for the formation of the local mode in ZnTe : Ni are analyzed within the concept of ionic-covalent character of ZnTe bonding, and the large width of the local mode resulting from its anharmonicity is discussed.
