摘要: Synchrotron radiation photoemission experiments with the disilicides of Ti, V, Nb, Cr, Fe, Co, and Ni are combined self-consistent augmented-spherical-wave calculations density states for metal silicides from Ca-Si to Cu-Si. These results demonstrate importance silicon $p$---metal $d$ bond formation extending \ensuremath{\sim}6 eV below ${E}_{F}$ all transition metals. Experiment theory show movement nonbonding above well At same time, antibonding Si $p$ $s$ shown be relatively insensitive particular atom in silicide series.
