Metal-insulator transitions are accompanied by huge resistivity changes, even over tens of
orders of magnitude, and are widely observed in condensed-matter systems. This article …

In the past decade intense research activity in the area of the so-called Ruddlesden-Poper
phases, especially the nickelates, has been motivated by the similarity of their structure and …

We report the discovery of a novel form of Ruddlesden–Popper (RP) nickelate that stands as
the first example of long-range, coherent polymorphism in this class of inorganic solids …

Transport in ultrathin films of LaNiO 3 evolves from a metallic to a strongly localized
character as the film's thickness is reduced and the sheet resistance reaches a value close …

The electronic structure of various nickel oxides with nickel valence varying from 1+ to 3+
was investigated with the aim to find similarities and differences to the isoelectronic …

The Ni ion in La Ni O 2 has the same formal ionic configuration 3 d 9 as does Cu in
isostructural Ca Cu O 2, but it is reported to be nonmagnetic and probably metallic whereas …

We have measured the oxygen positions in LaNiO 3 films to elucidate the coupling between
epitaxial strain and oxygen octahedral rotations. The oxygen positions are determined by …

In an effort to scale down electronic devices to atomic dimensions, the use of transition-metal
oxides may provide advantages over conventional semiconductors. Their high carrier …

We assess the performance of the Heyd-Scuseria-Ernzerhof (HSE) screened hybrid density
functional scheme applied to the perovskite family La MO 3 (M= Sc–Cu) and discuss the role …

Electrical resistivity and magnetotransport are explored for thin (3–30 nm), epitaxial LaNiO 3
films. Films were grown on three different substrates to obtain LaNiO 3 films that are …
