a Growth mechanism of SWCNTs using Fe seeds as growth templates. Adapted from [116]. b, c Atomic force microscope (AFM) images and height analysis of SWCNTs before the amplification process. Adapted from [116] and d, f after amplification growth process. Adapted from [116]. White arrows represent the original SWCNT seed location, red arrow indicates the seed position and angle relative to the locator inscription and yellow arrows show the entire length of the amplified nanotube.
