Abstract
A Gunn diode with a resonant-tunnelling cathode containing a quantum well with one energy level is considered. The use of such cathode leads to the fact that the current-voltage characteristics of the diode have two negative difference conductivity regions in either of which oscillations are possible. The oscillation efficiencies for both the regions are determined. The features of the operating diode is considered. The factors having an influence on the oscillation process have been analysed.
