- Journal:Applied Physics Letters
- Summary:The ballistic transport properties of Cu nanowires under different electric and stress fields are investigated for future application in microelectronics using first-principles density-function theory. Relative to the case with the electric field only, the stability and quantum conduction of both nonhelical and helical atomic strands are enhanced by applying a stress field F. Under V=1 V/Å, the most excellent quantum conductivity is exhibited at F= 1.5 nN for the nonhelical atomic strands while at F=2 nN for the helical ones, and the latter is more stable with collapse-resistant F high as 3 nN compared to the former as 2 nN.
