Abstract:

A recursive method is used to simulate the lattice dynamics of alpha-Al(2)O(3) crystals with F- and F(+)-centers in terms of the shell model. The local density of vibrations of atoms in the 1(st) and 2(nd) coordination spheres of a cluster comprising 1000 ions is calculated. Frequencies of defect-induced symmetrized vibrations are determined. The calculation results are compared with the data of the optical absorption in oxygen-deficient Al(2)O(3) crystals.
