Conductance histograms. a One-dimensional and b two-dimensional conductance histograms built from 2656 traces recorded for PDI8-CN2-based MCBJ devices. The curves are binned with 30 bins/nm on the x-axis, and 31 bins/decade on the y-axis. The color scale in the trace histogram indicates the density of data points found at each displacement and conductance value; in this way, the red areas represent the most probable evolution during the breaking process
