Abstract

The compositional dependence of the Ge-Ge mode in SnGe alloys was expressed in terms of a model that incorporates the basic physics of alloy mode frequencies in group IV alloys. Simple scaling laws that relate SnGe and GeSi vibrational modes were found. The existence of such scaling confirmed that SnGe alloys behave very similarly to the well-known GeSi alloys, in spite of the extreme differences between Sn and Ge.
