Abstract:
The third-order elastic constants, the pressure dependences of the second-order elastic constants, the Kleinman and Grüneisen parameters, and the thermal expansion coefficients have been estimated for nine IV–IV compounds and 13 III–V compounds using the Keating's and Harrison's models. The dependences of the results on the Phillips bond iconicity and the distance between the nearest neighbors are analyzed.
Keywords:
elastic constants, the Kleinman and Grüneisen parameters, thermal expansion coefficient.
