Abstract

Using a pseudo-potential approach within the virtual crystal approximation, the elastic properties of Y_xIn_1 – xN semiconductor ternary alloys in the hypothetical zinc-blende phase have been investigated. The results obtained for InN show a reasonable agreement with data available in the literature. Other case, our findings are the first predictions for alloys in question. The composition dependence of all features being considered in the present contribution for the material of interest has been analyzed and discussed. Our results have shown that the elastic constants and their related parameters for Y_xIn_1 – xN decrease monotonically with increasing the yttrium concentration x. The information derived from the present study may be useful for Y_xIn_1 – xN compositional characterization.

Y x In 1-x N三元系的弹性常数和相关的力学性能

摘要

在虚拟晶体近似中使用拟电位方法，研究了Y _x In _{1 –  x} N半导体三元合金在假定的闪锌矿相中的弹性性能。InN获得的结果与文献中的数据显示出合理的一致性。在其他情况下，我们的发现是有关合金的第一个预测。已经分析和讨论了在本贡献中考虑的所有特征对所关注材料的成分依赖性。我们的结果表明，Y _x In _{1 –  x} N的弹性常数及其相关参数随钇浓度x的增加而单调降低。。从本研究中获得的信息可能对Y _x In _{1 –  x} N的成分表征有用。
