      abstract     = {We investigated Raman vibrational modes in
                      silicon-germanium-tin layers grown epitaxially on
                      germanium/silicon virtual substrates using reduced pressure
                      chemical vapor deposition. Severalexcitation wavelengths
                      were utilized to accurately analyze Raman shifts in ternary
                      layers with uniform silicon and tin content in 4–19 and
                      2–12 at. $\%$ ranges, respectively. The excitation using
                      a633 nm laser was found to be optimal leading to a clear
                      detection and an unambiguous identification of all first
                      order modes in the alloy. The influence of both strain and
                      composition on these modes is discussed. The strain in the
                      layers is evaluated from Raman shifts and reciprocal space
                      mapping data and the obtained results are discussed in the
                      light of recent theoretical calculations.},
