From: Enhanced noise at high bias in atomic-scale Au break junctions
Excess noise at 3 G0 converted into voltage noise power SV as a function of bias.
The solid blue line is the best quadratic fit to the experimental data, while the dotted blue line is a systematic overestimate (see text) of the contribution of flicker noise at 1 G0. Any flicker noise contribution at 3 G0 is expected to be even smaller. Thus, flicker noise is unlikely to be a compatible explanation for the observed increase in noise as a function of V.
