a–d NW morphology at different growth durations: a 90 s; b 10 min; c 90 min; d 8 h. e Statistics of NW length, base diameter, and tip diameter at different growth durations. f TEM dark-field image of a segment of a bent NW. The image on the left is the high-resolution TEM image of the area indicated by the square. The three images at bottom are FFT of HRTEM images. The white lines are reference lines which have been set at the same position. Note that the diffraction spots move from left to right of the line as the FFT rotates clockwise
