For morphology-tunable synthesis of vertically-aligned single-walled carbon nanotube (VA-SWNT) arrays, we present a spin-coating catalyst-deposition method as an alternative to dip-coating, where cobalt and molybdenum metals are deposited onto Si substrates by spin-coating a solution containing 0.01 %wt of each metal species dissolved in ethanol. The array height and yield of the VA-SWNTs from this method are higher than that from dip-coating, however the resonance Raman spectra in the radial breathing mode region are similar. The VA-SWNT array height was found to be independent of the thickness of the spin-coated film over the investigated range, and the uniformity was optimized by tuning the spin-coating conditions.
