Lattice dynamics of β-SiC

Динамика решетки β-SiC

Il Nuovo Cimento B (1971-1996)

Summary

A six-parameter rigid-ion model for the lattice dynamics of zinc blende structure crystals is proposed. The proposed model is employed to calculate the phonon dispersion curves of β-SiC along high-symmetry directions. Noteworthy features of the present model lie in the fact that it satisfies the conditions of lattice invariance under rigid-body transformation and it reflects the dependence of the lattice sums on unpaired forces of the lattice.

Riassunto

Si propone un modello a ioni rigidi a sei parametri per la dinamica reticolare di cristalli di zincoblenda. Si impiega il modello proposto per calcolare le curve di dispersione dei fononi di β-SiC lungo direzioni ad alta simmetria. I comportamenti degni di nota di questo modello consistono nel fatto che esso soddisfa le condizioni di invarianza reticolare rispetto a trasformazioni di corpo rigido e riflette, la dipendenza delle somme di reticoli dalle forze reticolari spaiate.

Резюме

Предлагается моделя жесткото иона с шестью параметрами для динамики решетки кристаллов со структурой цинковой обманки. Предложенная модель используется для вычисления дисперсионных кривых β-SiC вдоль главных направлений симметрии. Заслуживаюшые внимания особенности предложенной модели состоят в следующем, модель удовлетворяет условиям инвариантности решетки относительно преобразований недеформируемого тела и моделя отражает зависимостя решеточных сумм от непарных сил решетки.
