The goal of this research was to obtain high-density single-walled carbon nanotube forests (SWNTs) on conductive substrates for different applications, including field emission.For this, dip-coating was chosen as the catalyst deposition method, to subsequently grow SWNTs by Alcohol Catalytic Chemical Vapor Deposition (AC-CVD).Si (100) was chosen as the substrate, which was color block iphone case then coated with a TiN thin film.By sputtering with Ar, it was possible to generate alternating TiN and Si lanes, with a different wettability and, therefore, a different affinity for the catalysts.

As a result, the Mo-Co catalyst was mainly deposited on 3 piece horse wall art TiN and not on sputtered-Si, which allowed the selective growth of SWNT forests on the TiN conductive surfaces.These as-synthesized SWNTs were used for field emission measurements in a high vacuum chamber.
