中文摘要	the room-temperature raman scattering studies of longitudinal optic phonons in alas/alxga1-xas and gaas/alxga1-xas short-period superlattices with different layer thicknesses were reported. the alas lo modes confined in alas layers and gaas-like lo modes confined in alxga1-xas layers were observed in alas/alxga1-xas superlattices under off-resonance conditions. and the gaas lo modes confined in gaas layers and alas-like lo modes confined in alxga1-xas layers were observed in gaas/alxga1-xas superlattices. in addition, the alas interface mode in alas/alxga1-xas was also observed under near-resonance conditions. based on the linear chain mode, the frequencies of confined lo modes measured by raman scattering were unfolded according to q=m/(n+1)(2 pi/a(0)) by which the dispersion curves of alas-like and gaas-like lo phonons in alxga1-xas mixed crystal were obtained.
