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.
