Freestanding copper nanowires (CuNWs) grown by CVD are analyzed by electron microscopy to show the details of a fivefold‐twinned structure. The electron diffraction pattern discloses irregular mismatching of the twin boundaries. The electron emission characteristics of the CuNWs are presented, along with a CuNW‐based proof‐of‐principle field‐emission display (see figure).
