ABSTRACT:
In a Gunn effect device the cathode contact is formed by an assembly of zones through which is effected the injection of current adjoining an assembly of zones which on the contrary are capable of blocking this injection. A layer of dielectric material possibly insulates these two types of zones. A metallic control electrode assures the arrival of the current. The respective dimensions of these zones are determined in such manner that, in operation, the injected current is channeled between parts of the device made dielectric by the creation of space charges.
