Figure 6From: Controlled growth of 1D and 2D ZnO nanostructures on 4H-SiC using Au catalystSEM images of ZnO NWs and Zn cluster drift phenomenon. SEM images of ZnO NWs grown for 10 min on high density of Au nanoparticles at (a) 850°C and (b) 900°C or on low density of Au nanoparticles at (c) 850°C and (d) 900°C. As pointed out by the arrows in (c), the ZnO NWs appear to protrude from the edges of the Au nanoparticles, while the arrows in (d) show the random motion of Zn cluster drift.Back to article page
