Abstract:	Model for simulation of the Brillouin spectra of three-dimensional regimented array of GeSi quantum dots in Si is proposed. We consider the low-energy part of the Raman spectrum that is determined by the transformed modes of three-dimensional folded acoustic phonons. These spectra are based on the phonon spectra found by numerical solution of elasticity equation. Shift and redistribution of intensity of Raman-active peaks depending on the composition of the GeSi solid solution, interdot distances, and quantum dot geometry are studied.
