Cluster Approximation for Disordered Systems. II : Effect of Short-Range Order
スポンサーリンク
概要
- 論文の詳細を見る
The effect of short-range order is studied numerically in a cluster approximation developed before by taking into account the cluster of five atoms. Calculations are performed on the density of states for vibrations in one-dimensional random lattice. It is found in the approximation that the shapes of peaky structure of the density of states are changed by the short-range order but the positions of the peaks are not so changed. Frequencies of localized levels for some clusters of impurity atoms are calculated exactly and the relation between these frequencies and the peaks obtained by the cluster approximation is discussed.
