Layer-resolved many-electron interactions in delafossite PdCoO2 from standing-wave photoemission spectroscopy

PdCoO2 belongs to a class of materials where both weakly and strongly correlated electrons co-exist side-by-side in different layers of the crystal structure. Here, the authors investigate PdCoO2 using standing wave photoemission spectroscopy and many-body calculations reporting layer-specific detai...

Sumario:PdCoO2 belongs to a class of materials where both weakly and strongly correlated electrons co-exist side-by-side in different layers of the crystal structure. Here, the authors investigate PdCoO2 using standing wave photoemission spectroscopy and many-body calculations reporting layer-specific details about the electronic structure.
