TEM image and the EDS spectra of an InSb NW. (a) TEM image of an InSb NW terminating with an indium droplet. The ‘1’, ‘2’, and ‘3’ circles indicate the regions where the EDS spectra shown in (b) are presented, respectively. (c) TEM image of a NW without a droplet on its end. The arrow indicates the region where the EDS spectra shown in (d) are acquired.
