高压下AlN纳米带的Raman光谱特性
In-situ High Pressure Raman Spectroscopy of AlN Nanobelt
摘要
Abstract
High pressure phase transition of AlN nanobelts was investigated in a range of 0-29.83 GPa by means of in-situ Raman spectrum method.According to the Raman scattering results,a pressure-induced wurtzite to rocksalt phase transition starts at 17.34 GPa and ends at 21.28 GPa.The Raman scattering of rocksalt AlN was assigned to the disorderly phonon scattering of rocksalt structure.In addition,the pressure dependence of vibration modes,the pressure coefficients and Grüneisen parameters were carefully calculated.关键词
