ABSTRACT
We have studied conductance characteristics of mechanically fabricated Ni nanoconstrictions under controlling electrochemical potential and pH of the electrolyte. The conductance histogram showed a clear feature peaked at 1–1.5 G0 (G0=2e2/h) when the potential of the constriction was kept at more negative potential than -900 mV versus Ag/AgCl at pH=3.7. A comparable feature also appeared at a more positive potential when a lower pH solution was used. We have revealed that Ni monoatomic contact or monoatomic wire can be stabilized in solution at room temperature under the hydrogen evolution.
