Abstract: |
The invention relates to an electron emitting component that includes a electron emitter that includes one dimension nanometer structure, a positive pole relative to the electron emitter, a first power supply to form a electric field between the electron emitter and positive pole, a second power supply to supply a heating voltage to electron emitter. The invention could heat electron emitter to generate emitting current. The heat voltage could remove the adsorbent on electron emitting surface to gain stable emitting current, and has low heating voltage that could conveniently adjust the heat current. |
