Electronic Structure of Superconducting FeSe Studied by High-Resolution Photoemission Spectroscopy
Rikiya Yoshida, Takanori Wakita, Hiroyuki Okazaki +13
We have performed soft x-ray and ultrahigh-resolution laser-excited photoemission measurements on tetragonal FeSe, which was recently identified as a superconductor. Energy depende…
Superconducting electronic state in optimally doped YBa2Cu3O7-d observed with laser-excited angle-resolved photoemission spectroscopy
M. Okawa, K. Ishizaka, H. Uchiyama +9
Low energy electronic structure of optimally doped YBa2Cu3O7-d is investigated using laser-excited angle-resolved photoemission spectroscopy. The surface state and the CuO chain ba…
Momentum dependence of the energy gap in the superconducting state of optimally doped Bi2(Sr,R)2CuOy (R=La and Eu)
Y Okada, T Takeuchi, M Ohkawa +5
The energy gap of optimally doped Bi2(Sr,R)2CuOy (R=La and Eu) was probed by angle resolved photoemission spectroscopy (ARPES) using a vacuum ultraviolet laser (photon energy 6.994…
Unusual Pseudogap-like Features Observed in Iron Oxypnictide Superconductors
Y. Ishida, T. Shimojima, K. Ishizaka +10
We have performed a temperature-dependent angle-integrated laser photoemission study of iron oxypnictide superconductors LaFeAsO:F and LaFePO:F exhibiting critical transition tempe…
