Fig. 6.15 Thickness dependent APECS a E 2p1/2 , b E 2p3/2 , c E k (LMM), and d E 3d5/2 spectra for
Ni films deposited on TiO 2 substrate. Atomic coordination reduction shifts the 2p core band and
the 3d valance band positively and the kinetic energy negatively. Reprinted with permission from

XPS, and APECS measurements verified consistently the BOLS expectation of Ni
skin quantum entrapment (Table 6.4).
