From: Large-scale and uniform preparation of pure-phase wurtzite GaAs NWs on non-crystalline substrates
HRTEM, the corresponding FFT images and EDS spectra. (a) and (c) are the HRTEM images and the corresponding FFT (insets) of the catalyst tip and NW body (scale bar = 5 nm); (b) and (d) are the EDS spectra of the catalyst tip and NW body in (a) and (c), respectively. It is also noted that the FFT of NW body in (a) is shown in (c) as the tip and the body are not observed under the same zone axis.
