Probing La-based nickelates with Ni 1 core-level photoelectron spectroscopy
Daisuke Takegami, Naoki Ito, Koto Fujinuma +15
We present a comparative Ni core level photoemission study of LaNiO, NdNiO, and LaNiO using both the Ni and the Ni . We address the challenges…
Oxygen on-site Coulomb energy in PrLaCeCuO and BiSrCaCuO and its relation with Heisenberg exchange
A. Chainani, M. Horio, C. -M. Cheng +20
We study the electronic structure of electron-doped PrLaCeCuO (PLCCO ; = 27 K, x = 0.1) and hole-doped BiSrCaCuO (Bi2212 ;…
Pressure suppression of the excitonic insulator state in Ta2NiSe5 observed by optical conductivity
H. Okamura, T. Mizokawa, K. Miki +9
The layered chalcogenide Ta2NiSe5 has recently attracted much interest as a strong candidate for the long sought excitonic insulator (EI). Since the physical properties of an EI ar…
Domain dependent Fermi arcs observed in a striped phase dichalcogenide
T. Mizokawa, A. Barinov, V. Kandyba +11
Angle-resolved photoemission spectromicroscopy on IrTe2 reveals evolution of mesoscopic striped domains across its first order phase transition at about 280 K. The striped texture…
CaCuRuO: a high Kondo-temperature transition metal oxide
D. Takegami, C. Y. Kuo, K. Kasebayashi +26
We present a comprehensive study of CaCuRuO using bulk sensitive hard and soft x-ray spectroscopy combined with local-density approximation (LDA) + dynamical mean-fi…
Direct observation of multiple conduction-band minima in high-performance thermoelectric SnSe
Mario Okawa, Yuka Akabane, Mizuki Maeda +14
We report time- and angle-resolved photoemission spectroscopy on SnSe which currently attracts great interest due to its extremely high thermoelectric performance. Laser-assisted p…
