The high-pressure behavior of wurtzite AlN nanowires is studied up to 51.1 GPa by in situ angle dispersive X-ray diffraction using synchrotron radiation source and a diamond anvil cell. With increasing pressure up to 24.9 GPa, the wurtzite-to-rocksalt phase transition was observed. The rocksalt phase is quenched after a complete pressure release. The axial ratio c/a of the wurtzite AlN nanowires decreases linearly with increasing pressure. The unique wire-like structure in AlN nanowires results in the high pressure behavior being different from that of the bulk and nanocrystal AlN.

利用金刚石对顶砧和同步辐射光源,对用电弧法制备的、具有纤锌矿结构的氮化铝(AlN)纳米线进行了最高压力达51.1 GPa的原位角散X射线衍射研究。结果表明:当压力上升至24.9 GPa时,纤锌矿结构的AlN纳米线开始向岩盐矿结构转变;当完全卸压后,最终的岩盐矿结构被保留下来;纤锌矿AlN纳米线的轴向比例c/a随压力增加而线性减小。AlN纳米线独特的线状结构决定了其区别于AlN微晶和AlN纳米晶的高压行为。

利用金刚石对顶砧和同步辐射光源,对用电弧法制备的、具有纤锌矿结构的氮化铝(AlN)纳米线进行了最高压力达51.1 GPa的原位角散X射线衍射研究。结果表明:当压力上升至24.9 GPa时,纤锌矿结构的AlN纳米线开始向岩盐矿结构转变;当完全卸压后,最终的岩盐矿结构被保留下来;纤锌矿AlN纳米线的轴向比例c/a随压力增加而线性减小。AlN纳米线独特的线状结构决定了其区别于AlN微晶和AlN纳米晶的高压行为。

The high-pressure behavior of wurtzite AlN nanowires is studied up to 51.1 GPa by in situ angle dispersive X-ray diffraction using synchrotron radiation source and a diamond anvil cell. With increasing pressure up to 24.9 GPa, the wurtzite-to-rocksalt phase transition was observed. The rocksalt phase is quenched after a complete pressure release. The axial ratio c/a of the wurtzite AlN nanowires decreases linearly with increasing pressure. The unique wire-like structure in AlN nanowires results in the high pressure behavior being different from that of the bulk and nanocrystal AlN.
