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 …

The vanadium oxides can exist in a range of single and mixed valencies with a large variety
of structures. The large diversity of physical and chemical properties that they can thus …

Core level spectroscopy has become a powerful tool in the study of electronic states in
solids. From fundamental aspects to the most recent developments, Core Level …

We report on a systematic analysis of x-ray photoelectron spectroscopy (XPS) core-and
valence-level spectra of clean and well-characterized iron oxide films, ie, α− Fe 2 O 3, γ− Fe …

Rhombohedral α− Fe 2 O 3 has been studied by using density-functional theory (DFT) and
the generalized gradient approximation (GGA). For the chosen supercell all possible …

We present a detailed ab initio investigation of the stability, the structural, electronic, and
magnetic properties of the (0001) surfaces of hematite (Fe 2 O 3) and chromia or eskolaite …

This review provides an overview of the different methods and computer codes that are used
to interpret 2p x-ray absorption spectra of 3d transition metal ions. We first introduce the …

The search for earth-abundant materials that can be used in solar water splitting cells
remains an important goal for affordable and environmentally friendly methods for energy …

We have performed photoemission and inverse photoemission experiments on a series of
3d-transition-metal oxides with formal ionic configuration from to. The photoemission core …

Polarization dependent x-ray-absorption measurements were performed on pure and Cr-
doped V 2 O 3 single crystals in the antiferromagnetic insulating, paramagnetic insulating …
