BEAM INSTABILITY AND AMPLIFICATION OF SPACE-CHARGE WAVES IN SEMICONDUCTOR PLASM

In the paper the amplification of space charge waves due to the plasma beam instability is considered. The beam is created by means of the resonant tunneling through a quantum well. The plasma beam interaction is described in terms of the hydrodynamic equations of two-component liquid. The increment of space charge wave has been calculated and the dependence of the increment on the different parameters also has been considered.
