Abstract: A study of the structural and quantum conductance properties of atomic-size copper nanowires generated by mechanical stretching was presented. The time-resolved electron microscopy observations and molecular dynamics simulations were used to derive the atomistic evolution. The quantum transport behavior was analyzed by means of conductance measurements and theoretical calculations. The formation of an unusual and highly pentagonal Cu nanowires with a diameter of ∼0.45 nm and ∼4.5 conductance quanta was also shown.
