The local atomic structure in GeSi alloys was studied experimentally and theoretically. By extended X-ray absorption fine structure measurements in Czochralski-grown Ge1-xSix bulk alloys, it is found that the Ge-Ge, Ge-Si (Si-Ge) and Si-Si bond lengths maintain distinctly different lengths and vary in a linear fashion as a function of alloy composition across the entire composition range 0<x<1, in good agreement with what is expected from the ab inito electronic structure calculations. It is known that both bond lengths and bond angles are distorted with alloy composition in GeSi.
