Topological surface electronic states in candidate nodal-line semimetal CaAgAs

Topological surface electronic states in candidate nodal-line semimetal CaAgAs

We investigate systematically the bulk and surface electronic structure of the candidate nodal-line semimetal CaAgAs by angle-resolved photoemission spectroscopy and density functional calculations. We observed a metallic, linear, non-k[subscript z]-dispersive surface band that coincides with the hi...
