中文摘要	the near-resonance raman scattering of gaas/alas superlattices is investigated at room temperature. owing to the resonance enhancement of frohlich interaction, the scattering intensity of even lo confined modes with a1 symmetry becomes much stronger than that of odd modes with b2 symmetry. the even modes were observed in the polarized spectra, while the odd modes appear in the depolarized spectra as in the off-resonance case. the second-order raman spectra show that the polarized spectra are composed of the overtone and combinations of even modes, while the depolarized spectra are composed of the combinations of one odd mode and one even mode. the results agree well with the selection rules predicted by the microscopic theory of raman scattering in superlattices, developed recently by huang and co-workers. in addition, the interface modes and the combinations of interface modes and confined modes are also observed in the two configurations.
