Query: Correlation between Quantum Conductance and Atomic Arrangement of Silver
  Atomic-Size Nanowires   We have studied the effect of thermal effects on the structural and transport
response of Ag atomic-size nanowires generated by mechanical elongation. Our
study involves both time-resolved atomic resolution transmission electron
microscopy imaging and quantum conductance measurement using an
ultra-high-vacuum mechanically controllable break junction. We have observed
drastic changes in conductance and structural properties of Ag nanowires
generated at different temperatures (150 and 300 K). By combining electron
microscopy images, electronic transport measurements and quantum transport
calculations, we have been able to obtain a consistent correlation between the
conductance and structural properties of Ag NWs. In particular, our study has
revealed the formation of metastable rectangular rod-like Ag wire (3/3) along
the (001) crystallographic direction, whose formation is enhanced. These
results illustrate the high complexity of analyzing structural and quantum
conductance behaviour of metal atomic-size wires; also, they reveal that it is
extremely difficult to compare NW conductance experiments performed at
different temperatures due to the fundamental modifications of the mechanical
behavior.
