Each system was equipped with a monochromatic Aluminum X-ray source which have a theoretical energy resolution limit of about eV.

5 The BEs for the ion etched Elements are reliable secondary energy The BEs of non-conductive materials are referenced to the hydrocarbon C 1s BE at eV to match current day methods of charge referencing, but this method of charge referencingis not absolute. The C 1s BEs of the adventitious hydrocarbon components on various naturally formed, thin native oxides (metal signal visible) were measured to occur between and eV. The native oxides of Ag, Al, Be, Bi, Cd, Co, Ga, Ge, Hf, In, Lu, Mg, Ni, Pb, Pd, Sc, Si, Ta, Y, Zn and Zr give C 1s BEs that are eV above eV. Surface dipole moments are suspected to be the cause of this shift. BEs of native oxides for these metals are more correct. BEs from oxides marked with a small red dot require further study. BEs for the chemical compounds should be accurate to ( ) ( )Copyrights 2007 XPS International LLC, all rights reserved.
