High-density two-dimensional electron system induced by oxygen vacancies in ZnO
T. C. Rödel, J. Dai, F. Fortuna +10
We realize a two-dimensional electron system (2DES) in ZnO by simply depositing pure aluminum on its surface in ultra-high vacuum, and characterize its electronic structure using a…

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…
