Depletion of density of states near Fermi energy induced by disorder and electron correlation in alloys

Han-Jin Noh, Tschang-Uh Nahm, Jae-Young Kim +4

We have performed high resolution photoemission study of substitutionally disordered alloys Cu-Pt, Cu-Pd, Cu-Ni, and Pd-Pt. The ratios between alloy spectra and pure metal spectra…
