In this overview, I will briefly explore some of the basic concepts and observable effects in X-
ray photoelectron spectroscopy, including references to some key first publications, as well …

Except in the very early stage of the development of X-ray photoemission spectroscopy
(XPS) by Kai Siegbahn and his coworkers, the excitation sources for XPS studies have …

Photoelectron spectroscopy has its roots in the Nobel Prize-winning work of Albert Einstein
and Kai Siegbahn. It is therefore both an honor and a humbling experience to produce a …

The electronic structure of ε-Ga 2 O 3 thin films has been investigated by ab initio
calculations and photoemission spectroscopy with UV, soft, and hard X-rays to probe the …

A large magnetic coupling has been observed at the La0. 7Ca0. 3MnO3/LaNiO3
(LCMO/LNO) interface. The x-ray photoelectron spectroscopy (XPS) study results show that …

We have reexamined the valence-band (VB) and core-level electronic structure of NiO by
means of hard and soft x-ray photoemission spectroscopies. The spectral weight of the …

The revolver undulator beamline BL15XU at SPring-8 has been constructed by National
Institute for Materials Science (NIMS). We have started hard X-ray photoemission …

The temperature (T)-dependent metal-insulator transition (MIT) in VO 2 is investigated using
bulk sensitive hard-x-ray (∼ 8 keV) valence-band, core-level, and V 2 p− 3 d resonant …

We have realized hard X-ray (HX) photoelectron spectroscopy (PES) with high-throughput
and high-energy-resolution for core level and valence band studies using high-energy and …

Stoichiometric FeRh undergoes a temperature-induced antiferromagnetic (AFM) to
ferromagnetic (FM) transition at∼ 350 K. In this Letter, changes in the electronic structure …
