Raman spectroscopy of CySi1-y alloys grown by molecular beam epitaxy
Abstract
Raman spectroscopy has been used to observe the C local mode in epitaxial CySi1-y layers grown by molecular beam epitaxy. The scattering cross section per C atom is independent of alloy concentration for y<2%. Lattice relaxation about substitutional C sites induces an extra peak near 475 cm-1.
