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.

Abstract
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.File in questo prodotto:
