Fig. 3: Comparison among experimental (blue line), simulated (red line) and model (black line) reflectance of ribbon arrays with width W = 2 μm and W = 1 μm PdCoO2.

Model and simulated reflectances are shifted along the y-axis with an offset of 0.1 and 0.3 (a), and 0.2 and 0.4 (b), respectively. The dip in the reflectance spectra is related to plasmon excitations at the PdCoO2–sapphire interface, the broad minima at a higher frequency to the PdCoO2–air interface.
