摘要：

We have examined resonance Raman scattering from bulk Bridgman-grown ZnTe, under excitation at eight photon energies covering 2.409 - 2.707 eV. Up to the 8th harmonic of the longitudinal optical (LO) phonon peak appeared, due to the outgoing resonance of LO phonons with the fundamental band gap. We compare the observed dependence of the intensity of the harmonics on order number m to a simple formula derived from the basic theory of Raman scattering, which includes a resonant term and a decreasing M-4 term. Polarization data support resonance Raman scattering as the origin of the multiphonon lines.
