Mn 3d derived contribution to the valence band of MBE grown cubic MnTe

Photoemission spectroscopy was applied to determine the valence band density-of-states in zinc blende MnTe grown by MBE on a CdTe(100) substrate. The Mn 3d derived contribution to the electronic structure was revealed by resonant photoemission experiments. Our experimental results are compared to the available configuration-interaction cluster models. An important role of the core hole screening (through charge transfer from ligand orbitals) on the whole Mn 3d derived photoemission spectrum (including the satellite structure observed below the valence band) was clearly confirmed.
