Abstract:
In this thesis, we are discussing the radiation impact on acoustic
wave that propagates along z-direction. The acoustic waves due to
radiation impact are investigated using the classical multi-fluid
approach in classical semiconductor plasma. The quantum effects
are not considered in this work. Our model is applied to GaAs
semiconductor plasmas.
Dispersion relation of acoustic waves is calculated where the
effects of the radiation modifies it. Numerically it is observed
under different physical conditions, for example, on varying the
thermal temperature values and plasma number density etc. For
this study we are using multi fluid model. A set of fluid equations
are applied to drive the dispersion relation. The said work is done
qualitatively and quantitatively using MATHEMATICA
