Van Hove singularities, chemical pressure and phonons: an angle-resolved photoemission study of KFeAs and CsFeAs
P. Richard, A. van Roekeghem, X. Shi +6
We report an angle-resolved photoemission spectroscopy (ARPES) study of KFeAs and CsFeAs, revealing the existence of a van Hove singularity affecting the electronic…

Observation of a nodal chain with Dirac surface states in TiB2
C. -J. Yi, B. Q. Lv, Q. S. Wu +13
Topological nodal-line semimetals (TNLSMs) are characterized by symmetry-protected band crossings extending along one-dimensional lines in momentum space. The nodal lines exhibit a…

Spatial-resolved X-ray photoelectron spectroscopy of Weyl semimetal NbAs
H. W. Liu, G. H. Zhang, P. Richard +3
We utilized X-ray photoemission electron microscopy (XPEEM) and X-ray photoelectron spectroscopy (XPS) to investigate the crystal surface of Weyl semimetal NbAs. XPEEM images prese…
