In situ time-resolved E-TEM observations of SWNT growth.
A time-sequence of four still E-TEM images (extracted from Supplementary Movie S2) of a Co-catalyzed SWNT grown at 600°C in presence of CO at 6.3 mbar. A time stamp accompanies each image. Insets: FFTs of the Co nanoparticle (framed) in each corresponding image, showing a negligible fluctuation in its crystal orientation during SWNT growth.
