Measurements of electronic band structure in CeCoGe${}_3$ by angle-resolved photoemission spectroscopy

Abstract

We report a comprehensive study of the electronic structure of CeCoGe${}_3$ 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: a surface state and folded bands, the latter which is argued to originate from a unit cell reconstruction.
