Abstract [en]

We investigate die dispersion property of a, low-frequency, electrostatic wave in a dense metallic electron-hole-ion plasma with nanoparticles. The latter are charged due to the Held emission, and hence the metallic can be regarded as charged dust rods surrounded by degenerate electrons and holes and non-degenerate ions. By using a quantum hydrodynamic model for the electrons and holes, we obtain the electron and hole number density perturbations, Mile be In awl dust rod number density perturbations follow the classical expressions. A dispersion relation for the low-frequency electrostatic wave in our multi-species dense metallic plasma 4 derived and analyzed. The possibility of exciting non-thermal electrostatic waves is also discussed.
