论文摘要
多元氮相的研究对于基本科学和新型高能密度材料的设计引起了极大的兴趣。在钻石砧细胞中140 GPA上纯氮的激光加热导致与黑磷结构BP-N合成聚合物氮同氮。使用同步加速器单晶X射线衍射原位鉴定该结构，并通过拉曼光谱和密度功能理论计算进一步研究。 BP-N的发现使氮与较重的PNICTEGEN元素保持一致，因此解决了关于聚合物氮相的不一致性，并提供了对极度密度的多元二氮排列的见解。
Studies of polynitrogen phases are of great interest for fundamental science and for the design of novel high energy density materials. Laser heating of pure nitrogen at 140 GPa in a diamond anvil cell led to the synthesis of a polymeric nitrogen allotrope with the black phosphorus structure, bp-N. The structure was identified in situ using synchrotron single-crystal X-ray diffraction and further studied by Raman spectroscopy and density functional theory calculations. The discovery of bp-N brings nitrogen in line with heavier pnictogen elements, resolves incongruities regarding polymeric nitrogen phases and provides insights into polynitrogen arrangements at extreme densities.
