Our Products


Our plug & play cold field emission source "NanoEmitter" grown on a support wire by means of electron beam induced processing combines a high density, diamond-like carbon core with high aspect ratio and tip sharpness, and a highly conductive coating. The precise fabrication process allows the batch-fabrication of self-stabilising emitters with stable emission characteristics at the desired sharpness, shape, mechanical stability and conductivity.
