We review oxygen K-edge X-ray absorption spectra of both molecules and solids. We start
with an overview of the main experimental aspects of oxygen K-edge X-ray absorption …

Layered Na-based oxides with the general composition of Na x TMO2 (TM: transition metal)
have attracted significant attention for their high compositional diversity that provides tunable …

The recent observation of superconductivity in N d 0.8 S r 0.2 N i O 2 has raised fundamental
questions about the hierarchy of the underlying electronic structure. Calculations suggest …

Perovskite nickelates (RNiO3, where R is rare earth or a heavy metal such as Tl or Bi)
display sharp metal–insulator transitions, unusual magnetic order, charge order and …

As the BO6 octahedral structure in perovskite oxide is strongly linked with electronic
behavior, it is actively studied for various fields such as metal–insulator transition …

In recent years, there have been significant efforts to understand the role of the electronic
structure of redox active materials according to their performance and thermodynamic …

We present a theory describing the local electronic properties of the perovskite rare-earth
nickelates—materials which have negative charge transfer energies, strong O 2 p–Ni 3 d …

The LiNi0. 5Mn1. 5O4 spinel is an appealing cathode material for next generation
rechargeable Li-ion batteries due to its high operating voltage of∼ 4.7 V (vs Li/Li+) …

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

In the past decade, the rapid development of modern heterointerface growth and
characterization techniques has stimulated great effort to research and design the …
