Abstract
A method for manufacturing a carbon nanotube (CNT) of a predetermined length is disclosed. The method includes generating an electric field to align one or more CNTs and severing the one or more aligned CNTs at a predetermined location. The severing each of the aligned CNTs may include etching the predetermined location of the one or more aligned CNTs and applying a voltage across the one or more etched CNTs.
