Measurements of Electronic Band Structure in CeCoGe3 by Angle-Resolved Photoemission Spectroscopy
In this paper, we present a comprehensive study of the electronic structure of CeCoGe3 throughout the entire Brillouin zone in the non-magnetic regime using angle-resolved photoemission spectroscopy (ARPES). The electronic structure agrees in large part with first principles calculations, including predicted topological nodal lines. Two new features in the band structure are also observed, namely a surface state and folded bands, the latter of which is argued to originate from a unit cell reconstruction.
