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…
Evidence for a cos(4φ) Modulation of the Superconducting Energy Gap of Optimally Doped FeTe_{0.6}Se_{0.4} Single Crystals Using Laser Angle-Resolved Photoemission Spectroscopy
K. Okazaki, Y. Ito, Y. Ota +10
We study the superconducting(SC)-gap anisotropy of the Γ-centered hole Fermi surface in optimally doped FeTe_{0.6}Se_{0.4} (T_c = 14.5 K), using laser-excited angle-resolved photoe…
Three-dimensional bulk band dispersion in polar BiTeI with giant Rashba-type spin splitting
M. Sakano, J. Miyawaki, A. Chainani +12
In layered polar semiconductor BiTeI, giant Rashba-type spin-split band dispersions show up due to the crystal structure asymmetry and the strong spin-orbit interaction. Here we in…
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…
