A THEORETICAL CALCULATION OF THE LOW-LYING BRANCHES OF PHONON DISPERSION RELATIONS FOR α-LiIO3
-
Abstract
A preliminary calculation for the low-lying branches of phonon dispersion relations of α-LiIO3 in directions 001, 100 and 110 using a simplified model are reported. In addition, we point out that coupling between different vibration modes may be important in lattice dynamics of such crystals.
