Evidence for bulk nodal loops and universality of Dirac-node arc surface states in ZrGeXc (Xc = S, Se, Te)
Takechika Nakamura, Seigo Souma, Zhiwei Wang +10
We have performed angle-resolved photoemission spectroscopy (ARPES) on layered ternary compounds ZrGeXc (Xc = S, Se, and Te) with square Ge lattices. ARPES measurements with bulk-s…
Nano-mosaic of Topological Dirac States on the Surface of Pb5Bi24Se41 Observed by Nano-ARPES
Kosuke Nakayama, Seigo Souma, Chi Xuan Trang +9
We have performed scanning angle-resolved photoemission spectroscopy with a nanometer-sized beam spot (nano-ARPES) on the cleaved surface of Pb5Bi24Se41, which is a member of the (…
Observation of Dirac-like energy band and ring-torus Fermi surface associated with the nodal line in topological insulator CaAgAs
D. Takane, K. Nakayama, S. Souma +10
One of key challenges in current material research is to search for new topological materials with inverted bulk-band structure. In topological insulators, the band inversion cause…
Three-dimensional band structure of LaSb and CeSb:Absence of band inversion
H. Oinuma, S. Souma, D. Takane +9
We have performed angle-resolved photoemission spectroscopy (ARPES) of LaSb and CeSb, a candidate of topological insulator. Using soft-x-ray photons, we have accurately determined…
Fermiology of possible topological superconductor Tl0.5Bi2Te3 derived from hole-doped topological insulator
C. X. Trang, Z. Wang, D. Takane +6
We have performed angle-resolved photoemission spectroscopy on Tl0.5Bi2Te3, a possible topological superconductor derived from Bi2Te3. We found that the bulk Fermi surface consists…
