Local order and hybridization effects for Mn ions probed by resonant soft x-ray spectroscopies: The Mn: CdTe(110) interface revisited

The electronic structure and the local ordering of Mn:CdTe?110? interface, produced by evaporating at room temperature ?RT? 2 ML of Mn on a CdTe?110? single-crystal surface, have been probed by soft x-ray spec- troscopies. Strong Mn-Te hybridization effects are found both in core level and valence-band photoemission spectra. The analysis of resonant photoelectron-diffraction patterns indicates that, already at RT, Mn atoms diffuse into CdTe down to the fourth layer, replacing the isovalent Cd atoms in the lattice.
