对非极性和半极性块状氮化铝（AlN）衬底在单轴应力下的反射光谱进行了研究。利用激子-极化子理论解释反射率谱，利用birr - pikus变形势理论分析激子跃迁能的应力依赖性。这种方法允许在没有准三次近似的情况下确定AlN中的所有变形势。
Reflectance spectroscopy was performed for nonpolar and semipolar bulk aluminum nitride (AlN) substrates under uniaxial stress. The exciton-polariton theory was applied to interpret the reflectivity spectra, while the Bir-Pikus deformation potential theory was used to analyze the stress dependence of exciton transition energies. This approach allowed all the deformation potentials in AlN to be determined without the quasicubic approximation.
