a Resistivity vs. temperature curve of monolayer RuO2 NSs (inset: SEM image of an individual RuO2 NS with four electrodes). b Experimental transmission spectra of monolayer RuO2 NS, CVD graphene, and a quartz substrate. The transmission spectra computed for distorted h-RuO2 and t-RuO2 and a transmission curve of distorted h-RuO2 scaled by a factor of 0.9882 are presented
