The spin configuration is vital for oxygen evolution reaction (OER) activity because it has a
strong effect on the adsorption/desorption ability of electrochemical reaction intermediates …

Perovskite-type transition metal (TM) oxides are effective catalysts in oxidation and
decomposition reactions. Yet, the effect of compositional variation on catalytic efficacy is not …

The wide tunability of strongly correlated transition metal (TM) oxides stems from their
complex electronic properties and the coupled degrees of freedom. Among the perovskite …

We employed operando soft X-ray absorption spectroscopy (XAS) to monitor the changes in
the valence states and spin properties of LaMn1–x Co x O3 catalysts subjected to a mixture …

We investigate the electronic structure of LaCoO 3 across the gradual spin-state and
insulator-to-metal transitions using bulk-sensitive hard x-ray photoelectron and soft x-ray …

The spin states of Co 3+ ions in perovskite-type LaCoO 3, governed by the complex
interplay between the electron-lattice interactions and the strong electron correlations, still …

Resonant inelastic x-ray scattering (RIXS) has become a very powerful experimental
technique to probe a broad range of intrinsic elementary excitations, for example, from low …

We present the cobalt 2p3d resonant inelastic X-ray scattering (RIXS) spectra of Co3O4.
Guided by multiplet simulation, the excited states at 0.5 and 1.3 eV can be identified as the 4 …

We report on the development of a high-resolution and highly efficient beamline for soft X-
ray resonant inelastic X-ray scattering (RIXS) located at the Taiwan Photon Source. This …

The fundamental idea of the excitonic insulator (EI) driven by electron–hole correlations in
narrow-gap semiconductors or semimetals was originally proposed in the 1960s, and only …
