1. A method of manufacturing an enhanced carbon nanotube (CNT) assembly, comprising:
- forming a CNT composite assembly comprising CNTs and particles of a transition metal, wherein forming the CNT composite assembly comprises;
providing a solution of CNTs plus transition-metal colloidal solution and dipping a metal tip into the solution;
adhering carbon nanotubes to the metal tip; and
withdrawing the metal tip from the CNT plus transition-metal colloidal solution so that the CNT composite assembly extends from the metal tip to CNT plus transition-metal colloidal solution, wherein the CNT composite assembly is formed without applying a voltage between the metal tip and the CNT colloidal solution; and
growing the CNT composite assembly, wherein growing the CNT composite assembly comprises a process selected from the group consisting of chemical vapor deposition, laser ablation and arc discharge,wherein the growth of the CNT composite assembly is facilitated by the particles of the transition metal.
