Abstract :
The effect of carrier drift on the dispersion properties and instability of longitudinal drift waves in infinite layered periodic structures is considered. We investigate the periodic structure composed of alternating layers of electron and hole semiconductors. It is assumed that the thickness of layers less than length of electromagnetic wave. In this case we can consider the structure as two-component plasma. It was shown that the plasma properties of the structure depend on the thicknesses of layers. The instability increments for the drift waves are determined.
