DEVICE FOR THE EXTRACTION OF ELECTRONS IN FIELD EMISSION SYSTEMS AND METHOD TO FORM THE DEVICE

摘要

The present invention relates to a device (1) for the extraction of electrons in field emission systems comprising a cathode (2) as electron source, a dielectric grid layer (3) and a conduction layer (4). The device (1) is in the form of a sandwich layered structure with cathode (2), grid layer (3) and conduction layer (4) arranged in the form of a stack. The invention further relates to a method to form the device (1) comprising steps forming the cathode (2) as electron source on one side of a dielectric substrate, forming the dielectric grid layer (3) within the substrate and forming the conduction layer (4) on the opposite side to the cathode (2) within the substrate.
