SEM images of InSb NWs grown on Si substrate. SEM image of the InSb NWs grown with (a) and without (b) InAs-seed-layer (tilt 45°); (c) side view of the InSb NWs showing a clear metallic droplet on their top. The inset (scale bar nm) shows the details on the final end of them (TEM); (d) the obtained InSb NWs without metallic droplet on the top. The inset shows details of this kind of NW (TEM).
