A resonant photoemission was used to study the ternary crystal formation, when small amount of Fe atoms was deposited (in one monolayer range of thickness) on the clean CdTe(100) surface. The constant initial state spectra taken near the Fe 3p-3d transition after Fe deposition and then again after heating process show the existence of two Fano-like resonance. The differences of the energy distribution curves taken for both resonance and antiresonance, respectively, allow us to distinguish two kind of Fe 3d contributions to the valence band: one derived from the metallic Fe islands on the surface and the second - derived from the Fe atoms built into the Cd1-xFexTe crystal.
