Figure 4From: Growth and characterization of gold catalyzed SiGe nanowires and alternative metal-catalyzed Si nanowires TEM image of a silicon NW ( T = 800°C, P SiH4 = 60 mTorr, P HCl = 60 mTorr, 30 min) with PtSi catalyst at the top. The image shows a clearly faceted catalyst, suggesting that it remains solid during growth.Back to article page
