Electronic structure and properties of transition-metal disilicides CoSi2, NiSi2 and their alloys CoxNi1-xSi2.

Kudrnovsky J., Christensen N.E.

An electronic-structure study of CoSi2, NiSi2 and their random substitutional alloys CoxNi1-xSi2, which all crystallize in the fluorite structure, is performed using the tight-binding linear muffin-tin orbital method within the coherent potential approximation to treat the effect of alloy disorder. The densities of states, energy bands for ordered crystals, and bloch spectral densities for alloys along symmetry lines, are presented. The effect of disorder on the transition metal sublattice on the electronic structure is discussed.
