Extended Data Fig. 8: Power dependence of the output DC voltage.
From: Quantized radio-frequency rectification in a kagome superconductor Josephson diode
The output DC voltage measured at \({I}_{{\rm{d.c.}}}\) = 0, \({B}_{{\rm{z}}}=-2.5\,{\rm{mT}}\) with frequency f of 0.4 GHz (a and c) and 0.6 GHz (b and d), respectively. At low rf power range, the frequency-normalized \({\widetilde{V}}_{{\rm{d.c.}}}\) exhibits a series of fractional voltage steps (a and b), while the integer voltage steps emerge one by one at higher rf powers.
