| Abstract: | Excitation of
modified electro-kinetic modes and novel properties introduced due to the
presence of negatively charged colloidal particles in otherwise compensated
semiconductor plasma are investigated. A compact linear dispersion relation for
the electro-kinetic waves in colloids laden semiconductor plasma has been
derived by using multi-fluid analysis and Maxwell’s equations. This dispersion
relation has been studied for slow and fast electro-kinetic modes. The presence
of charged colloids significantly modify the dispersion and absorption
characteristics of all possible modes even though colloidal particles, because
of their heavy masses do not participate in wave propagation. |
