Anomalous Compressibility and Electronic Robustness of Metallic Delafossite PdCoO${}_2$ under Pressure

Cheng Peng, Pahuni Jain, Tyler Harper +2

The layered delafossite PdCoO${}_2$ is an exceptional oxide metal whose ultrahigh conductivity arises from a Pd-derived nearly-free-electron band. Here, high-pressure single-crystal…
