Uniform field emission device
 A cold cathode field emission device is described. A key feature of its design is that groups of microtips share a single conductive disk with a reliable ballast resistor being interposed between each of these conductive disks and the cathode conductor. Additionally, a resistor, rather than a conductor, is used to connect the gate conductive disk to the gate electrode. The latter is arranged so as not to overlap with the cathode electrode. The cathode and gate conductive disks ensure that the ballast resistance associated with each microtip is essentially the same.
