| Abstract: | An analytical study
on excitation of acoustic waves and novel properties introduced by considering
that the implanted ions in a group III-V crystal agglomerate to form nanoclusters
(NCs) and some of them acquire negative charge in compensated piezoelectric
semiconductor plasma has been presented. By using multi-fluid analysis and
Maxwell’s equations, a compact dispersion relation for the acoustic wave in a
piezoelectric semiconductor has been derived. It is found that the presence of
charged NCs not only modifies the wave spectrum but also alters the
amplification characteristics even though NCs, on account of their heavy
masses, are assumed to be stationary in the background. |
