摘要：
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.
