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…
Terahertz Raman spectroscopy probe of intermolecular vibration in high-mobility organic semiconductors under uniaxial strain
Junto Tsurumi, Takayoshi Kubo, Hiroyuki Ishii +4
Terahertz Raman spectroscopy was performed on high-mobility organic single-crystal semiconductors, by which the phonon energy at the Gamma point was qualified as a function of exte…
Composition-induced structural instability and strong-coupling superconductivity in Au1-xPdxTe2
Kazutaka Kudo, Hiroyuki Ishii, Minoru Nohara
The physical properties and structural evolution of the MX-type solid solution AuPdTe are reported. The end member AuTe is a normal metal with a monoclinic…
Commensurate vs incommensurate charge ordering near the superconducting dome in IrPtTe revealed by resonant x-ray scattering
K. Takubo, K. Yamamoto, Y. Hirata +13
The electronic-structural modulations of IrPtTe (0 0.12) have been examined by resonant elastic x-ray scattering (REXS) and resonant inelastic x-ray…
Suppression of superconductivity and structural phase transition against pressure in Ca(IrAs)(FeIrAs)
Shunsaku Kitagawa, Shingo Araki, Tatsuo C. Kobayashi +5
We measured the pressure dependence of in-plane resistivity in the recently-discovered iron-based superconductor Ca(IrAs)(FeIrAs)$_{…
Pressure-Induced Superconductivity in Mineral Calaverite AuTe2
Shunsaku Kitagawa, Hisashi Kotegawa, Hideki Tou +4
The pressure dependences of resistivity and ac susceptibility have been measured in the mineral calaverite AuTe. Resistivity clearly shows a first-order phase transition into a…
Superconductivity Induced by Breaking Te2 Dimers of AuTe2
Kazutaka Kudo, Hiroyuki Ishii, Masaya Takasuga +5
Mineral calaverite AuTe2 is a layered compound with an incommensurately modulated structure. The modulation is characterized by the formation of molecular-like Te2 dimers. We have…
Flat-band excitonic states in Kagome lattice on semiconductor surface
H. Ishii, T. Nakayama, J. Inoue
Excitonic properties in the Kagome lattice system, which is produced by quantum wires on semiconductor surfaces, are investigated by using the exact diagonalization of a tight bind…
Photoemission study of the skutterudite compounds Co(SbTe) and RhSb
H. Ishii, K. Okazaki, A. Fujimori +3
We have studied the electronic structure of the skutterudite compounds Co(SbTe) (x= 0, 0.02, 0.04) by photoemission spectroscopy. Valence-band spectra revealed th…
