Abstract:
1. A method for the deposition and alignment of carbon nanotubes, comprising the steps of: providing an assembly that comprises a substrate having at least two electrodes supported thereon and opposing one another with a gap region being defined therebetween: depositing a carbon nanotube (CNT) attraction material on said substrate in said gap region; applying an electric potential to said two opposing electrodes wherein an electric field is generated across said gap region; wetting said CNT attraction material with a solution defined by a carrier liquid having carbon nanotubes (CNTs) suspended therein, wherein a first portion of said CNTs are aligned with said electric field and adhered to said CNT attraction material, and wherein a second portion of said CNTs are not adhered to said CNT attraction material; and removing said carrier liquid and said second portion of said CNTs from said assembly; wherein said CNT attraction material is a self-assembled monolayer.
