This review stands in the larger framework of functional materials by focussing on heterostructures of rare-earth nickelates, described by the chemical formula RNiO3 where R is a trivalent rare-earth R  =  La, Pr, Nd, Sm, …, Lu. Nickelates are characterized by a rich phase diagram of structural and physical properties and serve as a benchmark for the physics of phase transitions in correlated oxides where electron-lattice coupling plays a key role. Much of the recent interest in nickelates… 
Crossover between distinct symmetries in solid solutions of rare earth nickelates
A strong coupling of the lattice to functional properties is observed in many transition metal oxide systems, such as the ABO3 perovskites. In the quest for tailor-made materials, it is essential to
Tuning Photovoltaic Performance of Perovskite Nickelates Heterostructures by Changing the A-Site Rare-Earth Element.
Perovskite rare-earth nickelates (RNiO3) have attracted much attention because of their exotic physical properties and rich potential applications. Here, we report systematic tuning of the electronic

The fundamental properties of infinite-layer rare-earth nickelates (RNiO2) are carefully revisited and compared with those of CaCuO2 and RNiO3 perovskites. Combining first-principles and
Introduction to the Nickelates
Nickelates are one of the central families of the transition metal oxides, serving as a canonical example of the rich physics of TMOs. As perovskites, their chemical formula is RNiO\(_3\) where the R

First-principles study of electron and hole doping effects in perovskite nickelates
Rare-earth nickelates RNiO3 (R=Lu-Pr, Y) show a striking metal-insulator transition in their bulk phase whose temperature can be tuned by the rare-earth radius. These compounds are also the parent

Multiferroicity in rare-earth nickelates RNiO3.
TLDR
It is shown that charge ordered rare-earth nickelates of the type RNiO3 are multiferroic with very large magnetically-induced ferroelectric (FE) polarizations, and the small energy differences between the different magnetic orderings suggest that a chosen magnetic ordering can be stabilized by cooling the system in the presence of an electric field.

Modifying the electronic orbitals of nickelate heterostructures via structural distortions.
TLDR
A general materials design approach that produces large orbital energy splittings (orbital polarization) in nickelate heterostructures, creating a two-dimensional single-band electronic surface at the Fermi energy that mimics that of the high temperature cuprate superconductors.
Charge disproportionation without charge transfer in the rare-earth-element nickelates as a possible mechanism for the metal-insulator transition.
TLDR
The M-I transition may be viewed as being driven by an internal volume "collapse" where the NiO6 octahedra with two ligand holes shrink around their central Ni, while the remaining octaherra expand accordingly, resulting in the (1/2, 1/2) superstructure observed in x-ray diffraction in the insulating phase.
Metal-insulator transition in ultrathin LaNiO3 films.
TLDR
In the intermediate regime, quantum corrections to the Drude low-temperature conductivity are observed and negative magnetoresistance in this regime is isotropic, which points to magnetic scattering associated with the proximity of the system to either a spin-glass state or the charge ordered antiferromagnetic state observed in other rare earth nickelates.
