Photoemission Study of Mn-ZnTe(110) Interface

摘要

We have performed Mn 3p-3d resonant photoemission measurements on Mn-ZnTe(110) interfaces. The spectra for the Mn coverages below 1 A are similar to those of bulk diluted magnetic semiconductor Zn_(1-x)Mn_xTe alloys. The result suggests that the Mn deposition at room temperature onto ZnTe(110) surface leads the formation of surface Zn_(1-x)Mn_xTe alloys. The Mn 3d partial densities of states in the surface alloys are almost independent of the Mn concentration in agreement with the bulk alloys.
