Anomalous Compressibility and Electronic Robustness of Metallic Delafossite PdCoO under Pressure
Cheng Peng, Pahuni Jain, Tyler Harper +2
The layered delafossite PdCoO is an exceptional oxide metal whose ultrahigh conductivity arises from a Pd-derived nearly-free-electron band. Here, high-pressure single-crystal…

Mechanically Exfoliated Metallic Delafossite PdCoO2 Nanomembranes: Quantum Transport and Electrical Evaluation Toward Interconnect Applications
Chengyu Zhu, Pahuni Jain, Yi Zhang +6
Metallic delafossite oxides have drawn attention for their ultralow resistivity and coherent electronic transport. However, mesoscopic transport studies are hindered by the limited…

Dual Optical Hyperbolicity of PdCoO and PdCrO Delafossite Single Crystals
Salvatore Macis, Annalisa DArco, Eugenio Del Re +12
Hyperbolic materials exhibit a very peculiar optical anisotropy with simultaneously different signs of the dielectric tensor components. This anisotropy allows the propagation of e…
