One or more embodiments of the invention concern a device comprising: a cathode that lies on a cathode plane and includes, in an active region, one or more cathode straight-finger-shaped terminals with a main extension direction parallel to a first reference direction; for each cathode terminal, one or more electron emitters formed on, and in ohmic contact with, said cathode terminal; and a gate electrode that lies on a gate plane parallel to, and spaced apart from, said cathode plane, does not overlap the cathode and includes, in the active region, two or more gate straight-finger-shaped terminals with a main extension direction parallel to the first reference direction; wherein the gate terminals are interlaced with said cathode terminal(s).
