摘要

The characteristics of the structure of molten cadmium telluride were calculated using the method of molecular dynamics with the use of a Stillinger-Weber-type potential. The potential parameters adopted in Monte Carlo calculations of the structure of cadmium telluride were used. The molecular dynamics calculations were performed for an NVT ensemble at 1373 K. The results were compared with the neutron diffraction data. The Stillinger-Weber potential was shown to give an insufficiently accurate description of interparticle interactions in cadmium telluride melts. Its reparametrization was required to improve agreement with experiment.
