Abstract
We investigate the 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 field emission, and hence the metallic nanoparticles/nanotubes
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,
while the ion and dust rod number density perturbations follow the classical expressions.
A dispersion relation for the low-frequency electrostatic wave in our multispecies
dense metallic plasma is derived and analyzed. The possibility of exciting
non-thermal electrostatic waves is also discussed.
