Abstract

Autoionization electron emission from nickel in NiTi, initiated by electron-beam excitation is reported. It is the first observation of such electron-excited Ni emission, and unlike the case of elemental nickel, the feature is distinctly resolved from the Ni M_2,3VV Auger line. The measurements were done at temperatures corresponding to the CsCl-type phase of NiTi, and the emission intensity was found to depend critically on the annealing treatment of the sputter-cleaned sample. The appearance of Ni autoionization emission in Niti is attributed to changes in the distribution of the empty and filled d-states at the nickel sites on alloying with titanium. Emission energy shifts are estimated on the basis of reported theoretical band-structure calculations for NiTi.
