Fig. 5From: Development of a fully automated desktop chemical vapor deposition system for programmable and controlled carbon nanotube growthThree cases of CNTs having different areal densities and alignments grown by varying annealing times: The annealing times were set for a 5 min, b 10 min, and c 20 min. Left and right images show the top and sidewall SEM images of each case, respectively. Insets show the catalyst morphologies taken from blank runs for each caseBack to article page
