Image of FIG. 1.
FIG. 1.

CNT stack formation on (a) 0.5, (b) 1, (c) 2, and (d) 3 nm Fe thick samples. The white line indicates the stack boundaries, which are not seen clearly in the image. (e) The evolution of the CNT height with the growth time for the samples with different Fe thicknesses. The dotted lines are guidelines for the eye.

Image of FIG. 2.
FIG. 2.

CNT growth rate as a function of the growth time for samples with different Fe thicknesses. The dotted lines are guidelines for the eye.

Image of FIG. 3.
FIG. 3.

The inverse of the CNT growth rate as a function of square root of the growth time. The dotted lines represent the best linear fit to the data points.

Image of FIG. 4.
FIG. 4.

Parabolic rate constant as a function of Fe thickness. In the same graph, represents the Fe cluster diameter derived from the HRTEM analysis from Ref. 8. The shaded oval region indicates the longer sustainability of the catalyst for the CNT growth, and also shows linear tendency with the Fe thickness. The inset shows the 1.3 cm high CNT forest grown on the 1 nm Fe thick film after a growth time of 13 h.
