The cover picture shows a TEM image of a copper nanowire with a high density of traverse twins spontaneously formed by electrodeposition from a pure CuSO 4 electrolyte without the help of templates, surfactants, or additives. The twins are stacked perpendicular to the (111) plane of the wire with spacing of less than 1 nm. Micromechanical testing and electrical four‐probe measurements demonstrate that the highly twinned nanowires show a remarkably high mechanical strength whilst maintaining a high electrical conductivity, which is of great interest for applications in microelectromechanical systems.
