Charge transport of F4TCNQ with different electronic states in single-molecule junctions

Abstract

The molecular conductance of 2,3,5,6-tetrafluoro-7,7,8,8,-tetracyano-quinodimethane (F4TCNQ) with different electronic states (neutral, radical anion, and dianion) were investigated by scanning tunneling microscope break junction (STM-BJ) technique. These electronic states have distinct...

Suppressing the Conductance of Single-Molecule Junctions Fabricated by sp2 C–H Bond Metalation

“…The target fluorine-substituted arenes were synthesized via reported methods. First, the molecular conductance of S2 and S3 (for chemical structures, see Figures d,e and S1) was measured with the scanning tunneling microscope-based break junction (STM-BJ) technique under 400 mV. − As shown in Figure a, conductance plateaus are observed in the individual conductance traces of S2 and S3 . The logarithmically binned 1D conductance histograms of S2 and S3 display obvious conductance signals located at 10 –3.44 G 0 and 10 –5.56 G 0 , respectively (Figure b).…”

A bias voltage controlled electrode-molecule interface in single-molecule junctions

“…During measurements, we collected more than 3000 single traces to ensure the data reliability. [32][33][34][35][36] These traces were further used to plot 2D and 1D conductance histograms. As shown in Fig.…”

Reversible electric switching of NDI molecular wires by orthogonal stimuli

“…The conductance measurement was conducted according to the reported works in our group. 12,[23][24][25][26][27] To ensure the conductance is reproducible statistically, 2000 single conductance-displacement traces were collected for each sample. The traces are used to depict the one-dimensional (1D) conductance histograms and two-dimensional (2D) conductancedisplacement histograms.…”
