Softening of the Bond-Stretching Phonon of Ba1-xKxBiO3 at the Metal to Insulator Transition
H. Khosroabadi, S. Miyasaka, J. Kobayashi +4
The dispersion of phonons in Ba1-xKxBiO3 along the (3+q, 0, 0) direction in reciprocal space was determined for x=0, 0.30, 0.37, 0.52 using high-resolution inelastic X-ray scatteri…
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…
Carbon-substitution dependent multiple superconducting gap of MgB: a "sub-meV" resolution photoemission study
S. Tsuda, T. Yokoya, T. Kiss +10
``Sub-meV'' resolution photoemission spectroscopy was used to study carbon-substitution dependence on the multiple superconducting gap of Mg(BC. Two features c…
Raman study of carrier-overdoping effects on the gap in high-Tc superconducting cuprates
T. Masui, M. Limonov, H. Uchiyama +3
Raman scattering in the heavily overdoped (Y,Ca)Ba_2Cu_3O_{7-d} (T_c = 65 K) and Bi_2Sr_2CaCu_2O_{8+d} (T_c = 55 K) crystals has been investigated. For the both crystals, the elect…
Electronic structure of MgB from angle-resolved photoemission spectroscopy
H. Uchiyama, K. M. Shen, S. Lee +5
The first angle-resolved photoemission spectroscopy results from MgB single crystals are reported. Close to the K and M directions, three distinct dispersions are observe…
