The resonant Raman spectrum of a-Se bulk has been observed in the low frequency region and in the range of the wavelength 5145-6328 Å. The maximum of the resonance is centered at 5998 Å and shows a sharp peak at 31 cm−1 Stokes shift, whose intensity varies with wavelength. The experimental data were interpreted, and related to the behaviour of the derivative of the dielectric function in the same material.

Abstract
The resonant Raman spectrum of a-Se bulk has been observed in the low frequency region and in the range of the wavelength 5145-6328 Å. The maximum of the resonance is centered at 5998 Å and shows a sharp peak at 31 cm−1 Stokes shift, whose intensity varies with wavelength. The experimental data were interpreted, and related to the behaviour of the derivative of the dielectric function in the same material.File in questo prodotto:
