Abstract
Two lift-off techniques are demonstrated to form lateral field emissio n cathodes by shadowing a sputter deposition for tungsten composite. A current of 26 muA is observed for ''knife-edge'' cathodes of 23 mum e dge length. The I-V characteristics are consistent with the Fowler-Nor dheim relationship. The effect of focusing electrodes for increasing a node collection efficiency is consistent with our electron trajectory tracing simulations. The fabrication process for these devices is desc ribed in detail.
