六方系 InAlGaN 晶体的长波长光学声子研究
Study on Long-wavelength Optical Phonons in Hexagonal InAlGaN Crystals
摘要
Abstract
The optical phonons are investigated experimentally by means of Raman scatterning and by the modified random element isodisplacement (MREI) model in hexagonal quaternary nitride-based crystals.A one-mode behavior of E1 and A1 branches is presented in our calculated results.The calculated A1 (LO) branches are almost consistent with our experimental data for InxGa0.45-x Al0.55 N crystals,and Cros's experimenatal results for InxAl0.42-x Ga0.58 N crystals.关键词
