                      multi-component Cd$_{0.99}$Fe$_{0.01}$Te$_{0.97}$S$_{0.03}$
                      system were studied by means of X-ray absorption fine
                      structure (XAFS). Composition of non-polar (110) surfaces of
                      Cd$_{0.97}$Fe$_{0.03}$Te and
                      C$_{0.99}$Fe$_{0.01}$Te$_{0.97}$S$_{0.03}$ systems and
                      mechanism of their oxidation in ambient conditions were
                      studied by Atomic Force Microscopy (AFM) and X-ray
                      Photoelectron Spectroscopy (XPS). It has been found that Fe
                      preferentially substitutes Cd, but due to much smaller
                      covalent radius and preferences for paring with S, it causes
                      local distortion of the host CdTe lattice. The distortion is
                      confined to the Fe-immediate surrounding and the second and
                      third coordination shell atoms are (inside experimental
                      uncertainties) placed at distances expected in CdTe.
                      Although local structure around Fe is well defined in the
                      bulk of both samples, their near-surface region is
                      completely depleted from Fe, and in case of
                      Cd$_{0.99}$Fe$_{0.01}$Te$_{0.97}$S$_{0.03}$ somewhat
                      enriched in S. Special attention is, therefore, paid to
                      characterization of the near-surface region and evaluation
                      of its composition and structure. To that end we have
                      introduced a general standard-free algorithm for XPS data
                      analysis of the two-layer surface structure (bulk, oxide
                      layer, and the impurity layer). Results of the in-depth
                      composition analysis revealed that despite different bulk
                      composition and impurity layer thickness, underneath the
                      topmost impurity layer lays approximately one monolayer of
                      CdTeO$_3$ which passivates the surface.},
