Zusammenfassung

We employ first-principles alloy theories to assess the influence of local lattice distortions on the electronic transport of six body-centered cubic high-entropy alloys. We find weak disorder smearing of bands in the ideal lattice due to the similar number of valence electrons among alloying elements. Allowing relaxation, we demonstrate that local distortions in NbMoTaW and VNbMoTaW are small ...
