Field emission device using a reducing gas and method for making same

摘要

The invention concerns a device comprising at least one field effect electron source within a sealed structure, which encompasses an internal space that contains a reducing gas whose purpose is to prevent oxidation of the emissive material of the electron source, whereby the reducing gas is a gas with the formula N_xH_y where x=1 or 2 and y=3 or 4, and which is advantageously under a pressure of between 10^-8 and 10^-1 mbar. It also concerns manufacturing processes for such a device and apparatuses for implementing these processes.
