Raman Spectroscopy of Hg1-xMnxSe Alloys: Part II
In Part I of this paper, we used X-ray, far-infrared reflectivity and electron paramagnetic resonance measurements to investigate optical and magnetic properties of Hg1-xMnxSe (x≤0.26) alloys. In Part II, we expand our investigation to Raman spectroscopy and galvanomagnetic measurements. We registered two-mode behaviour of long wavelength optical phonons and described it by modified Genzel’s model. Except modes from the centre of Brillouin zone, there are some of forbidden modes in Raman spectra that originate from the edge of the zone, as well as a mode that corresponds to the maximum of phonon density of states. Modes of unalloyed α–MnSe are registered, too.
