Prolonged photo-carriers generated in a massive-and-anisotropic Dirac material
Munisa Nurmamat, Yukiaki Ishida, Ryohei Yori +8
Transient electron-hole pairs generated in semiconductors can exhibit unconventional excitonic condensation. Anisotropy in the carrier mass is considered as the key to elongate the…
Observation of a Hidden Hole-Like Band Approaching the Fermi Level in K-Doped Iron Selenide Superconductor
Masanori Sunagawa, Kensei Terashima, Takahiro Hamada +16
One of the ultimate goals of the study of iron-based superconductors is to identify the common feature that produces the high critical temperature (Tc). In the early days, based on…
Proving Nontrivial Topology of Pure Bismuth by Quantum Confinement
S. Ito, B. Feng, M. Arita +13
The topology of pure Bi is controversial because of its very small (10 meV) band gap. Here we perform high-resolution angle-resolved photoelectron spectroscopy measurements s…
Phonon-Dressed Two-Dimensional Carriers on the ZnO Surface
R. Yukawa, K. Ozawa, S. Yamamoto +8
Two-dimensional (2D) metallic states formed on the ZnO(100) surface by hydrogen adsorption have been investigated using angle-resolved photoelectron spectroscopy (ARPES).…
Ultrafast electron dynamics at the Dirac node of the topological insulator SbTe
Siyuan Zhu, Yukiaki Ishida, Kenta Kuroda +8
Topological insulators (TIs) are a new quantum state of matter. Their surfaces and interfaces act as a topological boundary to generate massless Dirac fermions with spin-helical te…
Fermi surfaces and orbital polarization in superconducting CeOFBiS revealed by angle-resolved photoemission spectroscopy
T. Sugimoto, D. Ootsuki, C. Morice +18
We have investigated the electronic structure of BiS-based CeOFBiS superconductor using polarization-dependent angle-resolved photoemission spectroscopy (AR…
