Evolution of local conductance pathways in a single-molecule junction studied using the three-dimensional dynamic probe method

“…Furthermore, understanding of the dynamics of the bonding states of molecules with electrodes while the molecular conformation is changed is particularly important for elucidating the details of electrochemical devices as well as molecular devices in which the reaction dynamics of the electrodes and molecules plays an important role, such as in fuel cells, catalysis and bioelectrochemical devices. [1][2][3][4] Such conduction properties of single molecules have been studied for various molecules by the break junction (BJ) method, and valuable results have been obtained. [5][6][7][8][9][10][11][12][13][14][15][16][17] However, in the BJ method, since the electrodes are connected and ruptured in each measurement, the junction structure is unknown and it is difficult to analyze whether the change in the measured conductance corresponds to the change in the conduction path due to the change in the contact structure or to the change in the transmittance due to the change in the molecular conformation.…”

Ag flake/silicone rubber composite with high stability and stretching speed insensitive resistance via conductive bridge formation

“…These researchers have made great progress in making highly stretchable and conductive conductors. However, for practical uses of these stretchable devices, there are new stability conditions, where the conductors are required to withstand thousands of stretching/contraction cycles and be independent of the stretching speed.From this point of view, self-healing polymer conductors are gaining more interest as a promising method to modify the stability of conductors [30][31][32] . Cracks are generated by repeated stretching/contraction cycles; this can make the conductive pathway longer, or even break it, making the conductor dielectric.…”
