We enrich a percolation-based picture for the basic understanding of the atypical two-modes behavior observed by Raman scattering in the Be-VI optical range of Zn1-xBex(Se,Te) alloys, with contrast in the bond stiffness. The attention is focused on the longitudinal optical (LO) Be-VI spectral region within the percolation regime (0.19
