(a) A plot of sheet resistance versus initial catalyst thickness of Co₂₀Fe₈₀ and Co₅₀Fe₅₀. The measurements were taken at room temperature. (b) Low density of MWCNTs grown on 4 nm Co₅₀Fe₅₀ catalyst thickness and (c) high density of MWCNTs grown on 6 nm Co₅₀Fe₅₀ catalyst thickness at 1.0 Torr gas pressure.
