Abstract :
The effect of carrier collisions on dispersion dependences and instabilities of drift waves in multilayered periodic semiconductor structure placed into external electrical field is considered in the work. It is supposed that the drift of different sign carriers under the influence of electrical field takes place. It is shown that the properties of drift waves depend on the direction of propagation and thicknesses of layers. It was received the conditions of wave instability.
