ABSTRACT:
In accordance with the invention, a field emission device is made by providing the device electrodes, forming a plurality of corrugated insulating rods with discontinuous coatings of conductive or semiconductive material with low secondary electron emission coefficient, adhering the rods to an electrode, cutting the rods to define corrugated pillars, and finishing the device. The result is low cost production of a field emission device having superior resistance to breakdown in high field operation.
