Journal ArticleDOI
Ordering of isovalent intersemiconductor alloys
TL;DR: Recent observations of spontaneous long-range ordering in alloys of isovalent semiconductors, despite independent evidence for repulsive interactions in these systems, are interpreted in terms of first-principles total-energy calculations for ordered compounds and cluster-variation-method calculations for the disordered phase.
Journal ArticleDOI
Overcoming doping bottlenecks in semiconductors and wide-gap materials
TL;DR: In this paper, the authors discuss how to find out what causes the doping bottlenecks in wide-band-gap materials where bipolar doping is impossible, and identify the main reasons for these bottlencesses as due mainly to the formation of intrinsic defects whose formation enthalpies depend on the Fermi energy.
Journal ArticleDOI
Mott gapping in 3 d A B O 3 perovskites without Mott-Hubbard interelectronic repulsion energy U
TL;DR: In this article, the authors show that the presence of band gaps in perovskite oxides with partially filled 3D shells has not been explained in terms of strong, dynamic interelectronic repulsion codified by the on-site repulsion energy U in the Hubbard Hamiltonian.
Journal ArticleDOI
Band structure and stability of zinc-blende-based semiconductor polytypes
TL;DR: In this paper, the band structure and stability of two types of zinc-blende-based polytype series were studied using a first-principles generalized one-dimensional Ising model.
Journal ArticleDOI
First-principles calculation of semiconductor-alloy phase diagrams.
TL;DR: Calcul de l'energie totale dans le formalisme de la densite locale et methode des agregats sur l'exemple de In x Ga 1−x P tenant compte des interactions chimiques et elastiques.
