Electric conductance of metal nanowires at mechanically controllable break junctions under electrochemical potential control
[摘要] We have developed the mechanically controllable break junction setup with an electrochemical cell (EC-MCBJ) to measure the electric conductance of metal nanowires under electrochemical potential control. The electric conductance of An nanowires was investigated in 0.1 M Na2SO4 solution using EC-MCBJ. The conductance of the Au nanowires was quantized in units of G(0) (=2e(2)/h), showing clear features in the conductance histogram. The atomic contact with a specific conductance value was kept for >5 s, indicating the relatively high stability of the present EC-MCBJ system. (c) 2007 Elsevier B.V. All rights reserved.
