Key Points

To investigate the electronic structure of CeCoGe3 using angle-resolved photoemission spectroscopy.
Conducted angle-resolved photoemission spectroscopy (ARPES) across the Brillouin zone.
Compared experimental data with first principles calculations.
Identified new features in the electronic band structure.
Confirmed electronic structure largely aligns with theoretical predictions.
Observed a new surface state within the band structure.
Identified folded bands attributed to a unit cell reconstruction.

Abstract

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.
