The amplification of a space‐charge wave in a semiconductor induced by the beam instability is considered. The electron beam is regarded as being injected out of the quantum well by means of resonant tunneling. The plasma‐beam interaction is treated in terms of the hydrodynamic equations of a two‐component liquid and the Poisson equation. The increment of SCW is calculated and the dependence of the increment on the different parameters such as temperature, carrier concentration, spacing of grating, and so on is also considered.
