Elastic constants and thermodynamic properties of zinc blende CuBr are calculated using a molecular dynamics simulation based on Tersoff empirical interatomic potential. We find that the elastic modulus C 11 is bigger than the other theoretical and experimental data, while C 12 is somewhat small. The elastic modulus C 44 is in good agreement with the theoretical calculations and experiment. Thermal expansion coefficient, specific heat capacity at constant volume and thermal conductivity are in very well agreement with experimental data. (© 2009 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
