Electronic states localized at step edges on Ni(7 9 11) surfaces studied by angle-resolved photoelectron spectroscopy

Abstract
Electronic states of Ni(7 9 11) surfaces were studied by angle-resolved ultraviolet photoelectron spectroscopy using synchrotron radiation the existence of a surface electronic state characteristic of the step and one associated with the terrace is shown from studies of the effect of alkali metal adsorption and the polarization dependence of photoelectron spectra.
