| 摘 要： | 文章基于密度泛函理论讨论了（闪锌矿结构（B3）和氯化钠结构（B1））GaN的晶体结构、相变压强和弹性性质。并用等焓原理获得B3→B1的相变压强为44．6Gpa，与相关的理论结果吻合较好。根据弹性模量与弹性常数的关系，详细讨论了B3→B1弹性性质随着压强的变化关系。

| Abstract: | The crystal structures.phase transition and elastic properties of GaN have been carried out based on density functional theory. Using the enthalpy-pressure data, we have observed the B3 to B1 structural phase transition pressure at 44. 6Gpa, it is well consistent with relevant theoretical results. According to the relation between elastic module and elastic constants, we study elastic properties of GaN with varying pressure in detail. |
