Strongly spin-orbit coupled two-dimensional electron gas emerging near the surface of polar semiconductors
M. Sakano, M. S. Bahramy, A. Katayama +12
We investigate the two-dimensional (2D) highly spin-polarized electron accumulation layers commonly appearing near the surface of n-type polar semiconductors BiTeX (X = I, Br, and…
Doping-dependent energy scale of the low-energy band renormalization in (Bi,Pb)2(Sr,La)2CuO6+d
Takeshi Kondo, Y. Nakashima, W. Malaeb +4
The nodal band-dispersion in (Bi,Pb)2(Sr,La)2CuO6+d (Bi2201) is investigated over a wide range of doping by using 7-eV laser-based angle-resolved photoemission spectroscopy. We fin…
Coexisting pseudo-gap and superconducting gap in the high-Tc superconductor La2-xSrxCuO4
T. Yoshida, W. Malaeb, S. Ideta +12
Relationship between the superconducting gap and the pseudogap has been the subject of controversies. In order to clarify this issue, we have studied the superconducting gap and ps…
Anomalous two peak structure in the Angle-resolved Photoemission Spectra of Ba1-xKxFe2As2
T. Shimojima, W. Malaeb, K. Ohgushi +13
The electronic structure near the Fermi level (EF) of Ba1-xKxFe2As2 (BaK122 ; x = 0.2 - 0.7) is studied using laser ultrahigh-resolution angle-resolved photoemission spectroscopy(A…
Abrupt change in the energy gap of superconducting Ba1-xKxFe2As2 single crystals with hole doping
W. Malaeb, T. Shimojima, Y. Ishida +17
We performed a Laser angle-resolved photoemission spectroscopy (ARPES) study on a wide doping range of Ba1-xKxFe2As2 (BaK) and precisely determined the doping evolution of the supe…
