A combined ion beam and molecular beam epitaxy (CIBMBE) method was applied for the deposition of a Ge 1-xC x alloy on Si(100) using a low-energy (50 - 100 eV) C + ion beam and a Ge molecular beam. Metastable Ge 1-xC x solid solutions were formed up to x = 0.047, and the CIBMBE method was shown to have a very high potential to grow metastable Ge 1-xC x alloys. It was also revealed that the sticking coefficient of C + ions into Ge was approx.28% for E i = 100 eV and approx.18% for E i = 50 eV. Structural characterization suggests that the deposited films are single crystals grown epitaxially on the substrate with twins on {111} planes. Characterization of lattice dynamics using Raman spectroscopy suggested that the deposited layers have a small amount of ion irradiation damage.
