“…The influence of the highly charged and massive colloids, formed within the ion-implanted semiconductor material, on the plasma properties, wave propagation characteristics, in finding the novel wave modes and in modification of existing plasma mode spectra is a subject of great current interest. Recently, this medium has attracted plasma and device physicists in finding the new modes of electro-acoustic [4], Alfven [5], electro-kinetic waves [6] and instability of acousto-electric wave [7] in colloids laden or ion-implanted semiconductor plasmas.…”

Using hydrodynamic model of inhomogeneous plasma, an analytical investigation of excitation of acousto-electric mode was made in n-type piezoelectric ion-implanted semiconductor plasma. By employing the multi-fluid balance equations along with the elastic and Maxwell equations, a compact dispersion relation for the cases in which colloidal grains are either stationary (ϑ 0d = 0) or streaming (ϑ 0d = 0) is derived. We find that the choice of homogeneous medium is favorable in achieving higher acoustic gain per radian and the results of the investigation should be useful in understanding the characteristics of longitudinal acousto-electric wave in ion-implanted piezoelectric semiconductor whose main constituents are electrons and negatively charged colloidal particles.
