Fig. 4: Charge transport properties of NDITTF-SHe.

a Logarithm-binned 1D histograms for NDITTF-SHe at an applied bias of 0.5 V. Inset: Molecular structure of NDITTF-SHe. b 2D conductance-displacement histograms for NDITTF-SHe at an applied bias of 0.5 V. All histograms are compiled from 10,000 traces without data selection. Inset: Normalized length profiles determined from the 2D histogram. c Junction structures with different binding sites used to compute the junction transmission functions. d Transmission functions against energy of the two types of junctions.
