Influence of stress on the field emission properties of amorphous carbon thin films and multiwall carbon nanotube-polymer composites

Abstract

This work investigates the effects of stress on carbon-based materials during field emission. Amorphous carbon films containing nano-crystalline particles and MWNT composite thin films are subjected to external stress by mechanical bending. The samples were bent using an optical fibre placed in the middle of the sample. Field emission properties were measured using the probe technique.
