Unconventional superconductivity in the BiS-based layered superconductor NdOFBiS
Yuichi Ota, Kozo Okazaki, Haruyoshi Q. Yamamoto +8
We investigate the superconducting-gap anisotropy in one of the recently discovered BiS-based superconductors, NdOFBiS ( 5 K), using laser-bas…
High-resolution three-dimensional spin- and angle-resolved photoelectron spectrometer using vacuum ultraviolet laser light
Koichiro Yaji, Ayumi Harasawa, Kenta Kuroda +8
We describe a spin- and angle-resolved photoelectron spectroscopy (SARPES) apparatus with a vacuum-ultraviolet (VUV) laser (= 6.994 eV) developed at the Laser and Synchrotron R…
Superconductivity in an electron band just above the Fermi level: possible route to BCS-BEC superconductivity
Kozo Okazaki, Yoshiaki Ito, Yuichi Ota +10
Conventional superconductivity follows Bardeen-Cooper-Schrieffer(BCS) theory of electrons-pairing in momentum-space, while superfluidity is the Bose-Einstein condensation(BEC) of a…
Orbital-dependent modifications of electronic structure across magneto-structural transition in BaFe2As2
T. Shimojima, K. Ishizaka, Y. Ishida +12
Laser angle-resolved photoemission spectroscopy (ARPES) is employed to investigate the temperature (T) dependence of the electronic structure in BaFe2As2 across the magneto-structu…
Observation of superconducting gap in boron-doped diamond by laser-excited photoemission spectroscopy
K. Ishizaka, R. Eguchi, S. Tsuda +13
We have investigated the low energy electronic state of a boron-doped diamond thin film by the ultrahigh resolution laser-excited photoemission spectroscopy. We observed a clear sh…
