First-principles study of electron and hole doping in perovskite nickelates
Lucia Iglesias, Manuel Bibes, Julien Varignon
Rare-earth nickelates RNiO (R=Lu-Pr, Y) show a striking metal-insulator transition in their bulk phase whose temperature can be tuned by the rare-earth radius. Th…
Origins Vs. fingerprints of the Jahn-Teller effect in d-electron ABX perovskites
Julien Varignon, Manuel Bibes, Alex Zunger
The Jahn-Teller (JT) distortion that can remove electronic degeneracies in partially occupied states and results in systematic atomic displacements is a common underlying feature t…
Magnetism tailored by mechanical strain engineering in PrVO thin films
Deepak Kumar, Adrian David, Arnaud Fouchet +8
Transition-metal oxides with an ABO perovskite structure exhibit strongly entangled structural and electronic degrees of freedom and thus, one expects to unveil exotic phases a…
Origin of band gaps in 3d perovskite oxides
Julien Varignon, Manuel Bibes, Alex Zunger
With their broad range of magnetic, electronic and structural properties, transition metal perovskite oxides ABO3 have long served as a platform for testing condensed matter theori…
Mott gapping in 3d ABO3 perovskites without Mott-Hubbard interelectronic U
Julien Varignon, Manuel Bibes, Alex Zunger
The existence of band gaps in Mott insulators such as perovskite oxides with partially filled 3d shells has been traditionally explained in terms of strong, dynamic inter-electroni…
Bond disproportionation, charge self-regulation and ligand holes in s-p and in d electron ABX3 perovskites by density functional theory
Gustavo Martini Dalpian, Qihang Liu, Julien Varignon +2
Some ABX3 perovskites exhibit different local environments (DLE) for the same B atoms in the lattice, an effect referred to as disproportionation, distinguishing such compounds fro…
