SEM images of (a) catalyst pattern seen on oxide coated Si wafer prior to the growth of SWCNTs. Adapted from [202]. b Long, well-oriented SWCNTs grown using fast-heating growth process with Fe/Mo nanoparticles, CO/H2 900 °C for 10 min. Inset shows the magnified image of the SWCNT arrays formed. Adapted from [202]. c Well aligned arrays of SWCNTs (~ 5 SWCNTs μm−1) formed by CVD growth on a ST-cut quartz substrate. Adapted from [207]. d AFM image of aligned SWCNTs grown on r-plane (1 1 0 2) crystalline surfaces of sapphire. Adapted from [206]
