| 1. A method comprising the steps of:
a) contacting a carbon nanotube (CNT) fiber with a metal surface to form a CNT-metal interface;
wherein the contacting step comprises translating the CNT fiber to the metal surface; and
wherein the CNT fiber contacts the metal surface at an end of the CNT fiber; and
b) heating the CNT-metal interface in an etching atmosphere at a temperature that permits catalytic etching of the end of
the CNT fiber to provide an end-etched CNT fiber.
