通过第一性原理计算，揭示了锌尖晶石和纤锌矿结构二元化合物的微观结构与压电性能之间的关系。定义了表征结构不对称程度的结构参数P和θ。它们被发现是线性的压电常数e14和e33的锌尖晶石和纤锌矿结构的二元化合物，分别。
First-principles calculations were performed on binary compounds of zinc-blende and wurtzite structures to disclose the relationships between the piezoelectric performance and the microscopic structure. The authors defined the structure parameters P and θ to represent the degree of asymmetry in structure. They were found to be linear to piezoelectric constants e14 and e33 for zinc-blende and wurtzite structure binary compounds, respectively.
