- Summary:The ballistic transport properties of Cu nanowires under different bending stresses are investigated for future application in flexible displays and flexible solar cell using first-principles density-function theory. The stability and quantum conduction of both nonhelical and helical atomic strands are reduced by applying a bending stress f. With increasing of f, the helical wire becomes disorder, suffering a phase transition to the nonhelical one and collapsing eventually. Our calculations show that the maximum bearable bending stress is fmax = 3 nN for the helical atomic strands, while is more stable than fmax = 2.5 nN for the nonhelical atomic strands.
