| Abstract: | We have studied the optical properties of silicon with incorporated nanocrystallites of semiconducting magnesium silicide
by optical spectroscopy and Raman spectroscopy. We have calculated the optical functions of samples grown with different numbers
of layers of incorporated magnesium silicide nanocrystallites. We have determined the contribution of magnesium silicide to
the electronic structure of multilayer samples in the photon energy range 1.5–3.0 eV. We have studied the phonon structure
of the grown multilayer samples, based on analysis of two-phonon and three-phonon resonances in silicon and Mg2Si.
