Native defects in tetradymite Bi2(TexSe3−x) topological insulators
Formation energies of native defects in Bi2(TexSe3-x), with comparison to ideal Bi2Te2S, are calculated in density-functional theory to assess transport properties. Bi2Se3 is found to be n type for…

On the structural chemistry of gamma-brasses: two different interpenetrating networks in ternary F-cell Pd-Zn-Al phases.
TLDR
Electronic structure calculations, using the tight-binding linear muffin-tin orbital atomic-spheres approximation (TB-LMTO-ASA) method, on models of these new, ternary gamma'-brass phases indicate that the observed chemical compositions and atomic distributions lead to the presence of a pseudogap at the Fermi level in the electronic density of states curves, consistent with the Hume-Rothery interpretation of gamma-brasses, in general.
