Abstract
Building successful
devices based on carbon field emitters requires a fundamental understanding of
emitter behavior during field emission.
Detailed investigations of the field emission behavior of individual
single-walled and multi-walled nanotubes have shown several properties that are
particularly important for devices. We
describe these properties which include adsorbate interactions, current
saturation, field evaporation, and environmental degradation, and we discuss
their impact on the design of field emission devices. We then describe challenges and recent progress in the
development of large area field emission sources.
