Abstract
Disclosed herein is a triode-type field emission device, in particular for high frequency applications, having a cathode electrode, an anode electrode spaced from the cathode electrode, a control gate electrode arranged between the anode electrode and the cathode electrode, and at least a field-emitting tip; the cathode, control gate and anode electrodes overlapping in a triode area at the field-emitting tip and being operable to cooperate with the field-emitting tip for generation of an electron beam in the triode area. The cathode, control gate and anode electrodes do not overlap outside the triode area, and have a main direction of extension along a respective line; each of these respective lines being inclined at a non-zero angle with respect to each one of the others.
