摘要：

A model is proposed describing the bond length and bond-bending angle distributions in quaternary A(3)B(5) alloys with ZB structure in quasi-continuum approximation. The model allows to consider reasonably large crystal lattice clusters employing minimum computing resources. Analytical expressions are derived for the radial distribution functions. The developed approach is applied to the analysis of available experimental data on structural disorder in Ill-V alloys. Employing the valence force field Keating model the deformation energy for several alloys is evaluated. (C) 2003 Elsevier Ltd. All rights reserved.
