“…Acoustic probing is another method for researching the dissipative structure. It is well known [14][15][16][17][18][19] that a pronounced acoustoelectric effect is observed in Te. In a high electric field when the carrier drift velocity v d becomes higher than the phase velocity of sound v s , phonons are generated which interact with the charge carrier in the crystal.…”

It is experimentally shown that in bulk InSb and Te single crystals, during the formation and excitation of the dissipative structure in the non-equilibrium electron-hole plasma, in the case of a presence of longitudinal autosolitons, the carrier concentration decreases outside the autosolitons, while it increases in the case of transverse autosolitons. The longitudinal autosolitons, forming in the non-equilibrium electron-hole plasma by Joule heating, are considered to be cold, and the transverse autosolitons to be hot.

“…After the seminal papers on collective effects or plasma like behavior in solids [9,10], the detailed characteristics of the normal modes were investigated theoretically. It is extensively reported in literature [11][12][13] that the interplay between the acoustic waves and carriers lead to three novel effects due to the momentum and energy exchange between the carriers and lattice ions; these effects are (i) the amplification or attenuation of acoustic waves, (ii) the electrons will tend to shield out any electric field produced due to elastic deformation which will modify the elastic constant and thus the speed of sound and (iii) the electrons experience an additional force due to the transfer of momentum from the sound wave which gives rise to the so called electroacoustic field that causes the electroacoustic current in semiconductors.…”

Cusp solitons in piezoelectric semiconductor plasmas

Using the semi-classical model, the piezoelectric coupling of Langmuir waves with lattice ion vibrations has been studied in linear as well as nonlinear regime in n-type piezoelectric semiconductors. It is shown that there is not any significant coupling in the linear regime. In the nonlinear regime, we have developed a set of coupled nonlinear evolution equations whose solution leads to cusp solitons. These equations are analyzed numerically to investigate the conditions for the significant coupling using the standard parameters for n-type piezoelectric semiconductor plasmas.

“…Most of the theore experimental work in nonlinear acoustics on this topic has been limited t harmonic generation [1][2][3] or parametric interactions [4,5] or has included th of an applied external electric field [1][2][3][4][5][6]. The latter can give rise to amplific other effects, as has been described in several reviews [7][8][9] and tends to exponential growth of certain modes over all others…”
