文摘

In this paper, we use Ag as a probe to compare the conductance of the NCs created by STM-based jump-to-contact and crash-to-contact approaches with the results of theoretical modeling reported in the literature. It is shown that the jump-to-contact created Ag NCs have most probable conductance at 1, 2 and 3 G₀, with that at 2 G₀ most abundant, which is in agreement with theoretical modeling. It is thus proved that metal Ag NCs created by jump-to-contact STM-BJ bear well-defined structures.
