Figure 3From: Growth and characterization of gold catalyzed SiGe nanowires and alternative metal-catalyzed Si nanowires SEM images of PtSi-catalyzed Si NW grown for 30 min at various temperatures: (a) 500°C, (b) 700°C, (c) 800°C. PSiH4 is held constant at 60 mTorr. The NW grown at 700 and 800°C show a tapered shape, whereas the diameter of the NW grown at 500°C is constant (45 nm).Back to article page
