a, Device schematic. The device is the same as the one in Fig. 1b, except that BG2 has been replaced by a top gate (TG) to apply a transverse displacement field, as shown schematically in the right-hand panel. b, Excess thermal noise SI measured as a function of the source current for two cases: (1) νBG = 4 and νTG = 4 (red) and (2) νBG = 4 and νTG = 0 (black) at D ≈ −0.08 V nm−1 (see Supplementary Fig. 7 for details). c, JQ (solid circles) as a function of \({T}_\mathrm{M}^{2}-{T}_{0}^{2}\). The blue solid line represents the linear fit with GQ = 8κ0T.
