Researchers announced today that they have built a nanowire that is 2.6 nanometers long, shows an unusual increase in conductance as the wire length increases, and has quasi-metallic properties.

The team measured “tunneling currents” across this nanogap to estimate the conductivity through the DNA junctions against an empty nanogap that does not contain DNA, in “break-junction ...

Aside from interlayer conductivity, the vertical conductivity can be probed using conductance atomic force microscopy (c-AFM), where the results showed similar trends for diverse 2-D materials ...
