Observation of a bulk 3D Dirac multiplet, Lifshitz transition, and nestled spin states in Na3Bi
Su-Yang Xu, Chang Liu, S. K. Kushwaha +20
Symmetry or topology protected Dirac fermion states in two and three dimensions constitute novel quantum systems that exhibit exotic physical phenomena. However, none of the studie…
Spin-polarized angle-resolved photoelectron spectroscopy of the so-predicted Kondo topological insulator SmB6
Shigemasa Suga, Kazuyuki Sakamoto, Taichi Okuda +13
Undoped and slightly Eu-doped SmB6 show the opening of a gap with decreasing temperature below ~150 K. The spectral shapes near the Fermi level (EF) at 15 K have shown strong incre…
Realization of bulk insulating property and carrier manipulation in reversible spin current regime of the ideal topological insulator TlBiSe2
Kenta Kuroda, Gaku Eguchi, Kaito Shirai +10
The surfaces of three-dimensional topological insulators (TIs) characterized by a spin-helical Dirac fermion provide a fertile ground for realizing exotic phenomena as well as havi…
Experimental verification of the surface termination in the topological insulator TlBiSe using core-level photoelectron spectroscopy and scanning tunneling microscopy
Kenta Kuroda, Mao Ye, Eike F. Schwier +10
The surface termination of the promising topological insulator TlBiSe has been studied by surface and bulk sensitive probes. Our scanning tunneling microscopy has unmasked fo…
Unoccupied topological surface state in BiTeSe
Munisa Nurmamat, E. E. Krasovskii, K. Kuroda +10
Bias voltage dependent scattering of the topological surface state is studied by scanning tunneling microscopy/spectroscopy for a clean surface of the topological insulator BiT…
