Modified interactions of longitudinal phonon–plasmon in magnetized piezoelectric semiconductor plasmas

Effect of Density Gradient on the Acousto-Electric Wave Instability in Ion-Implanted Semiconductor Plasmas

“…Very recently, the present authors have reported an analytical study on excitation of modified electro-acoustic modes and its absorption characteristics in n-type homogeneous semiconductor plasma embedded with colloidal grains [4]. In this report authors found a strong resonant interaction between the acoustic mode and a colloidal particles-modified electro-kinetic mode due to the piezoelectric nature of the medium.…”

“…Motivated by the fascinating works of Ghosh et al [4,17,18] in the present paper we intend to report the investigations made on the dispersion and absorption characteristics of phonon-plasmon mode in inhomogeneous colloids laden semiconductor plasma. The interaction between electrons and lattice vibrations is one of the fundamental interaction processes in solids; it gives useful information regarding the physical properties of the host medium.…”

“…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.…”

Dispersion and Absorption of Longitudinal Electro-Kinetic Waves in Magnetized Ion-Implanted Semiconductor Plasmas

“…Very recently, the present authors have reported analytically the instability of new electro-kinetic [1,2], electro-acoustic waves [3,4] and the modifications in existing wave spectra in colloids laden semiconductor plasma medium. The investigations in Refs.…”

Phonon-Plasmon Interactions in Inhomogeneous Semiconductor Plasma Embedded with Nanoparticle Cluster

“…As we have discussed above, this particle drift is the only parameter which actually decides the amplification/attenuation of the acoustic wave while propagating through a semiconductor medium. Recently, many investigators have reported their efforts of investigating acoustic wave amplification in homogeneous [19][20][21] as well as inhomogeneous [22][23][24][25] semiconductor plasma medium under several physical regimes and field geometries.…”
