Morphology of the in-plane CuO nanowires. SEM images of the in-plane CuO nanowires synthesized at various temperatures (a, b, c, d). The distributions of the mean diameter of the nanowires obtained from a portion of the SEM image (e). The solid lines represent the fitting curves assuming the log-normal function, where <d> is the mean diameter of the nanowires.
