This paper analyses the atomic correlations in crystalline and amorphous Si and Ge and discusses their relationship. Expressions for the atomic correlations are presented. On the basis of the theory, a 400-atom structural model for a-Ge has been constructed. The main characteristics of the model are in good agreement with experimental results.
