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 …

Filled skutterudite compounds with a chemical formula AT4X12 (A= rare earth, actinide,
alkaline, or alkaline earth elements; T= Co, Ni, Rh, etc.; X= pnictogen) have been intensively …

The valence and core levels of In 2 O 3 and Sn-doped In 2 O 3 have been studied by hard x-
ray photoemission spectroscopy (h ν= 6000 eV) and by conventional Al K α (h ν= 1486.6 eV) …

Electronic structures of the quantum critical superconductor β-YbAlB 4 and its polymorph α-
YbAlB 4 are investigated by using bulk-sensitive hard x-ray photoemission spectroscopy …

We have examined the valence-band electronic structures of gold and silver in the same
column in the periodic table with nominally filled d orbitals by means of a recently developed …

N-type bismuth vanadate (BiVO4) has emerged as one of the most promising photoanodes
for use in water-splitting photoelectrochemical cells in recent years. However, its …

accepted September 11, 2009; published November 25, 2009) The lattice specific heat Clat
of La-based filled skutterudites LaT4X12 (T ¼ Fe, Ru and Os; X ¼ P, As, and Sb) has been …

The microscopic mechanism of heavy band formation, relevant for unconventional
superconductivity in CeCoIn5 and other Ce-based heavy fermion materials, depends …

We present a single-crystal study of low-temperature magnetism and transport in Sm T r 2 Al
20 (T r= Ti, V, and Cr). Strong valence fluctuation is manifested as Kondo effects, including a …

The electronic properties of surfaces and buried interfaces can vary considerably in
comparison to the bulk. In turn, analyzing bulk properties, without including those of the …
