摘要：
A study of Raman scattering by longitudinal optical phonons in GaAs/AlAs superlattices with ultrathin AlAs layers has made it possible to observe scattering by odd and even localized LO phonons simultaneously. An explanation for this result is proposed: a mechanism of Raman scattering due to defects.
