The electronic structure of transition metal oxides featuring correlated electrons can be
rationalized within the Zaanen-Sawatzky-Allen framework. Following a brief description of …

Vertically aligned nanocomposite thin films with ordered two phases, grown epitaxially on
substrates, have attracted tremendous interest in the past decade. These unique …

Oxide electronic materials provide a plethora of possible applications and offer ample
opportunity for scientists to probe into some of the exciting and intriguing phenomena …

The wide spectrum of exotic properties exhibited by transition-metal oxides stems from the
complex competition between several quantum interactions,. The capacity to select the …

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 …

We study a model for the metal-insulator (MI) transition in the rare-earth-element nickelates
R NiO 3, based upon a negative charge transfer energy and coupling to a rocksaltlike lattice …

We experimentally demonstrate a novel approach to substantially modify orbital occupations
and symmetries in electronically correlated oxides. In contrast to methods using strain or …

At interfaces between conventional materials, band bending and alignment are classically
controlled by differences in electrochemical potential. Applying this concept to oxides in …

Improving the efficiency of charge separation (CS) and charge transport (CT) is essential for
almost all optoelectronic applications, yet its maximization remains a big challenge. Here we …

We use the variational mean-field approach to systematically study the phase diagram of a
bilayer heterostructure of the correlated transition-metal oxide LaNiO 3, grown along the …
