(a) Conductance measured for different values of V tip and d tip for the tip centered above the middle of the central branch (see Fig. 1a) V BG = 3.8 V. (b) Derivative of G with respect to d tip corresponding to the mapping (a). (c) Derivative of G with respect to V tip at constant V BG associated to the G mappings similar to Fig. 3b but realised for d tip = 140 nm. The slope labelled ‘Coulomb blockade’ is identical to the slope 1 presented in Figs. 3c and 4c. We also reported the slope 2 identified on Fig. 3c obtained with d tip = 50 nm (black dashed line) to compare with the slope observed with d tip = 140 nm (blue dashed line). All horizontal axes are matched.
