Large area gridded field emitter arrays using anodised aluminium

Abstract:

We report a novel non-lithographic technique to produce gridded field emitter arrays. Porous anodic alumin membranes with well-defined pores (approximate to 160 nm) and high pore density have been exploited to fabricate a very high density of filed emitters (approximate to 55 x 10(8) cm(-2)). An additional advantage is offered by the small size of the individual emitter devices (approximate to 160 nm grid aperture), allowing operation with only moderate extraction voltages. The lowest extract...
