✦ Synopsis

ReceEved 23 September 19;4 core level bindins energies of metals in the f&king alloys and t%etaldispers&d or -implanted materizls have beeri studied: Au-&,

Pt-Ag, Pt-C and Au-SiOz. Their shifts from the binding energiej of pure species (referenced to the Fermi level) are interpreted to consist of a matrix shift result@ from differences in crystat field potential, tel.z=tion enera" znd work function as well z.5~ chemical shift due to differences in v&ence electron density. Bjr estimatin:: tIte tisti shift us@ implanted A.r in the related pure materials, the chemical shift could be isolated frcim the observed binding energy &ift. In all cases studied, the matrix shift is greater *&an rhe chemical shift and its contribution to the binding energy shifts is in tie opposite direction.
