Figure 2From: Dysprosium-Catalyzed Growth of Single-Walled Carbon Nanotube Arrays on Substratesa A representative AFM image of SWNTs at long oriented area; b the corresponding topographic height profile along the black line in part a; c diameter distribution of the SWNTs obtained from AFM measurements of 118 SWNTs. Gaussian fit is done and given the mean diameter of 1.336 nmBack to article page
