Changes in the surface electronic structure upon martensitic   transformation in TiNi and TiPd
  The electronic structure of some low index surfaces for martensitic B19'-TiNi and B19-TiPd were investigated using the full-potential linearized augmented plane wave method. The alteration of the electronic structure upon martensitic transformation on the surface were analyzed. According to the surface calculations only insignificant changes in the electronic structure near the Fermi level were found as for bulk ground state. The formation of oxides top layers is also discussed. It is shown that the influence of TiNi substrate is insignificant when three oxides layers are formed.
