The generation of macroscopic electron beam currents through vacuum field emission from a large number of emission sites requires a surface with a complex microstructure. To date, the fabrication of surfaces suitable to this task has been dominated by microlithographic techniques. In these process, masks are used in conjunction with etching or deposition techniques to produce arrays of micron-scale cones or wedges. Patent applications.
