Abstract:
A carbon nanotube field emitter comprises at least two electrodes and at least one graphitized carbon nanotube structure. The at least one graphitized carbon nanotube structure comprises a first end and a field emission end. The first end is opposite to the field emission end. The first end is fixed between the at least two electrodes, and the field emission end is exposed from the at least two electrodes and configured to emit electrons.
