Abstract
A Gunn diode comprises deposited in succession on the active zone of gallium arsenide of type N: a first layer of the same material having the same type of conductivity but very strongly doped, and a second layer of amorphous germanium in which is developed a tunnel effect. A metallic deposit covering this second layer serves as cathode contact.
