A scanning tunneling microscope is used to form a connective neck of atomic size between a lead substrate and a lead tip. The elongation and contraction of the neck results in a regular and reproducible staircase structure in the tip-substrate conductance vs tip-displacement curve, giving physical insight on the plastic and elastic deformation mechanisms involved in atomic-scale structures.
