      abstract     = {We present element-specific effective bond-stretching force
                      constants and Einstein frequencies of (In,Ga)P ternary
                      alloys determined by temperature-dependent extended x-ray
                      absorption fine structure spectroscopy. The bond-stretching
                      force constants of both bond species show a nearly linear
                      composition dependence between the values of GaP and InP. In
                      contrast, the corresponding Einstein frequencies are
                      different for the two bond species over the whole
                      compositional range. Furthermore, we demonstrate that the
                      composition dependence of bond-stretching force constants
                      and Einstein frequencies for (In,Ga)P, (In,Ga)As, and
                      Zn(Se,Te) is mostly caused by the associated bond length
                      changes. Remaining deviations may be explained by coupling
                      effects between different bond species within the alloy.},
