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.

摘要

使用基廷和哈里森模型估算了九种IV-IV化合物和13 III-V化合物的三阶弹性常数，二阶弹性常数的压力依赖性，Kleinman和Grüneisen参数以及热膨胀系数。 。分析了结果对Phillips键象似性和最近邻居之间距离的依赖性。
