Abstract
High direct currents of 2.0 mAmps for a 15 micron diameter single walled nanotube (SWNT) fiber were achieved. Highly aligned, dense SWNT morphology in the fiber was demonstrated to reduce threshold emission and improve resilience to Joule heating. SWNT fibers were exposed to ion bombardment and the effects on emission were evaluated.
