(a) AFM analysis of 1 nm Fe deposited onto TiN and pretreated for 5 min at under PP in 100 mbar of and a dc plasma power of 50 W . [(b) and (c)] SEM images of 1 nm Fe deposited onto TiN and pretreated by TP and PP, respectively, at . (d) Histograms showing lateral size distribution with Gaussian fitting (red solid lines) of nanoparticles obtained in (b) and (c).

Image of FIG. 3.
FIG. 3.

SEM images of CNTs grown for 10 min in 0.5 mbar of on (a) Fe and (b) Co films receiving PP; (c) Ni and (d) Co films following TP. For (a), (c), and (d), the growth temperature is , but for (b) it is .

Image of FIG. 4.
FIG. 4.

HRTEM of CNTs grown on TiN/Fe films receiving PP. Growth conditions are for 10 min in 0.5 mbar of . CNTs have parallel and continuous walls.

Image of FIG. 5.
FIG. 5.

SEM images of CNTs grown for 10 min in 0.5 mbar of at on Fe with (a) TP and (c) PP, with supply of hydrocarbon for , stopped for 5 min, and restarted for another 5 min. (b) and (d) are schematics of the growth processes for TP and PP, respectively.
