Electric-field-enhanced assembly of single-walled carbon nanotubes on a solid surface

A novel electric field-enhanced chemical assembly approach for fabricating highly aligned single-walled carbon nanotube (SWNT) arrays on a solid surface with remarkably improved efficiency and packing density is reported. The molecular dynamics simulation results clarified the alignment of SWNTs with their long axes along the electric flux in solution, leading to the increase of packing density and efficiency through overcoming the steric hindrance of the 'giant' carbon nanotubes.
