Field emission device having emission-inducing and suppressing gates |
摘要 |
A field emission device including a cathode having an electric field emitter for emitting electrons, a field emission inducing gate for inducing electron emission, and an anode for receiving the emitted electrons. A field emission suppressing gate is interposed between the cathode and the field emission inducing gate for suppressing electron emission, so that problems such as gate leakage current, electron emission due to anode voltage, and electron beam spreading of the conventional field emission device are significantly overcome.
