Tactile-Feedback Stabilized Molecular Junctions for the Measurement of Molecular Conductance

Handling the (AFM) tip: The duration of stable molecular junctions was prolonged using a tactile feedback method in which the operator can sense the force of the AFM tip on the sample surface (see picture). The movement of the tip is adjusted accordingly, maintaining a more consistent current (i) an...

Summary:Handling the (AFM) tip: The duration of stable molecular junctions was prolonged using a tactile feedback method in which the operator can sense the force of the AFM tip on the sample surface (see picture). The movement of the tip is adjusted accordingly, maintaining a more consistent current (i) and voltage (V), instead of having the tip move at a constant preset speed, as in the conventional setup.
