Abstract

The electronic structure of monocrystalline ZnTe was investigated for a clean, relaxed (110)-(1 x 1) surface and for the same surface after sequential deposition of Mn atoms. The resonant (Fano-type) photoemission technique was applied. The spectra were measured as energy distribution curves and in the constant initial state mode, for the valence band and Zn 3d core level. At very low Mn coverage (theta < 0.15 nm), manganese interaction with the crystal surface results in creation of ternary alloy Zn1-x,Mn-x,Te(110) surface. Further increasing of Mn deposition leads to formation of metallic manganese islands on the surface. The successive annealing leads to Mn atoms diffusion and to formation of Zn1-x,Mn,Te at the surface region.
