ABSTRACT:
A field emission device (10) is made with a lateral emitter (100) substantially parallel to a substrate (20) and with a simplified anode structure (70). The lateral-emitter field-emission device has a thin-film emitter cathode (100) which has a thickness not exceeding several hundred angstroms and has an emitting blade edge or tip (110) having a small radius of curvature. The anode's top surface is precisely spaced apart from and below the plane of the lateral emitter and receives electrons emitted by field emission from the blade edge or tip of the lateral-emitter cathode, when a suitable bias voltage is applied. The device may be configured as a diode, or as a triode, tetrode, etc. having one or more control electrodes (140) positioned to allow control of current from the emitter to the anode by an electrical signal applied to the control electrode. In a particularly simple embodiment, a single control electrode (140) is positioned in a plane above or below the emitter edge or tip (110) and automatically aligned to that edge. The simplified devices are specially adapted for use in arrays, including field emission display arrays.
