(a) Normalized resistance of the 3.4-nm metallic sample as a function of the scaling variable 
at indicated temperatures (for clarity, only seven temperatures are shown). Inset: The fitting of a power law to the inverse temperature dependence of dR/dB at Bc. (b) Normalized resistance of the identical metallic sample as a function of the scaling variable 
at indicated electric fields (for clarity, only five electric fields are shown). Inset: The fitting a power law to the inverse electric field dependence of dR/dB at Bc.
