Abstract

We present a detailed analysis of the compositional dependence of the average over(E, ̄)1 of the E1 and E11 transition energies in Ge1-x-ySixSny alloys. We show that this dependence can be explained in terms of three bowing parameters-bSiGe, bGeSn, and bSiSn-which scale with the product ΔχΔR of the Phillips electronegativity and size mismatches between Si, Ge, and Sn.
