Samples featuring Sn content up to 13 at.% were analyzed by x-ray absorption fine structure spectroscopy at the Sn-K edge. The study reveals how the growth method and its process parameters, like temperature, or the epitaxial built-up strain affect the local atomic ordering of tin within the alloys. While the deposition technique seems to have a marginal effect on the Sn short-range ordering, the growth temperature and Sn content systematically influence the bonding angles Sn. Ge-Sn next neighbor coordination shells, whereas the interatomic distances remain largely unaffected. In the first coordination shell Sn-Ge are strongly favored over Sn-Sn, while the opposite happens in the next coordination shell, where Sn-Sn are systematically favored. These insights into the relationship of growth condition and layer properties enable to identify the nature of the large variety of electronic and optical properties measured in\n
