The Korringa–Kohn–Rostoker Green's function method within the coherent-potential
approximation was applied to calculate the electronic properties of recently synthesised
semi-Heusler TiCo1− xNixSb solid solution. As evidenced parallel from electrical resistivity
measurements, the calculations confirm a semiconductor type behaviour for TiCoSb
compound and a metallic type one for alloys containing Ni. The electronic conductivity was
found to originate from the d-electrons of Ti, Co and Ni, mainly.
