Figure 6From: Growth and characterization of gold catalyzed SiGe nanowires and alternative metal-catalyzed Si nanowires SEM images of NiSi-catalyzed NW grown at 800°C for 10 min with different HCl partial pressures: (a) no HCl, (b) P HCl = 40, (c) PHCl = 100, (d) P HCl = 160 mTorr. The lengths of straight NW are 4 μm for (c) and 8 μm for (d).Back to article page
