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.American Institute of Physics2005-07engjournal articleVoRhttp://hdl.handle.net/2115/5913http://www.aip.org/https://doi.org/10.1063/1.20011420003-6951APPLIED PHYSICS LETTERS87043104https://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/5913/1/APL87-4.pdfapplication/pdf136.17 KB2005-07
