XPS study of glassy Pd80Ge20

An X-ray photoemission and Auger electron spectroscopy study of the electronic structure of Pd₈₀Ge₂₀ alloy in its glassy and crystalline states is reported. The glassy state shows some modifications in the valence band structure, symmetry of the Pd $\text{3}\text{d}{}_{\mathrm{<mtext>3</mtext><mtext>2</mtext>}}\text{?3}\text{d}{}_{\mathrm{<mtext>3</mtext><mtext>2</mtext>}}$ spin-orbit doublet and a shift in M₄₅-V-V Auger transition of Pd. Analysis of the chemical shifts in the core-level binding energies of the constituents indicates negligible charge transfer from the metalloid atom (Ge) to d-band of the Pd.
