When the photon energy of an incident light is close to E0+Δ0 of Hg1-xCdxTe, 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” TO2 mode from the principal (100) face of Hg1-xCdxTe in the case of no resonant scattering; and also analyzed the reason why the “forbidden” TO2 mode from the principal (100) face of Hg1-xCdxTe 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 Fr?hlich interaction.
