Electronic structure of the Mn/Cd_(0.96)Zn_(0.04)Te(111) interface studied by synchrotron radiation

摘要

The formation and electronic structure of Mn/Cd_(0.96)Zn_(0.04)Te(111) have been investigated by photoemission with synchrotron radiation. It is determined that Mn grows on Mn/Cd_(0.96)Zn_(0.04)Te(111) in a two-dimensional mode at early stage. The possibility that the magnetic ordering state exists in the ultra-thin Mn film is proposed. With increasing Mn coverage, Mn atoms interdiffuse to the substrate and the exchange reaction between Mn and Cd is observed. The features of the spectra show that the Cd_(1-x)Mn_xTe phase is formed at the interface. At high coverage of Mn, bulk α -Mn becomes dominant
