Modification in dispersion characteristics of space charge wave in a semiconductor plasma medium due to presence of nanoparticle cluster has been reported. This study has been conducted using classical hydrodynamic model of infinite plasma. The obtained dispersion relation has been analyzed to study convective nature of two possible propagating space charge modes. This study resulted in a strong modification in dispersion characteristics of space charge wave in an n-type semiconductor plasma medium embedded with a nanoparticle cluster/assembly. This modification is through a non-dimensional parameter ‘l’; characteristic of nanoparticle cluster, which is a function of nanoparticle density N and radius r. It is hoped that, reported study in the considered media will make it very suitable for the use as a probe for solid state diagnostics.
