LONGITUDINAL PHONON-PLASMON INTERACTIONS IN QUANTUM SEMICONDUCTOR PLASMAS WITH NON-PARTICIPATING COLLOIDS

Using the quantum hydrodynamic model for quantum semiconductor magnetoplasma, the acousto-electric wave spectrum has been investigated in detail in presence of non-participating negatively charged colloidal grains in addition to usual electrons and holes. The present analysis predicts that the quantum correction and presence of non-participating charged colloids significantly affect the wave spectrum of acousto-electric mode in semiconductor plasmas.
