Abstract:

The effects of differently charged Ge impurities on the local atomic structure and lattice dynamics of a -quartz were studied. We have determined the equilibrium structures and calculated the symmetrized local density of vibrational states for the Ge-doped a -quartz. The frequencies of localized vibrations of A- and B -symmetries induced by Ge impurities were obtained. Besides, we have analyzed what contribution the vibrations of atoms located around the Ge impurities make to the localized symmetrized vibrations.
