Title: RESONANT RAMAN SCATTERING OF Hg_(1-x)Cd_xTe
Abstract: When the photon energy of an incident light is close to E\-0+Δ\-0 of Hg 1- x Cd x Te, we observe the resonant Raman scattering, “forbidden” resonant enhancement Raman scattering and the second\|order resonant Raman scattering. We have analyzed the reason why we can observe the weak “forbidden” TO 2 mode from the principal (100) face of Hg 1- x Cd x Te in the case of no resonant scattering; and also analyzed the reason why the “forbidden” TO 2 mode from the principal (100) face of Hg 1- x Cd x Te increases significantly in the case of no resonant scattering. According to our analysis, we find that the second\|order resonant Raman scattering by two LO phonons is caused largely by the interband Frhlich interaction.
