When dust particles are created in a radio-frequency processing discharge or when they are introduced from outside, they obtain a negative charge due to the large mobility of the electrons. A high dust density therefore changes the discharge characteristics, not only by the presence of an almost immobile charge, but also because there is a continuous loss of ions and electrons by recombination at the surface of the dust particles. In this paper we use a 1D Particle-In-Cell plus Monte Carlo model to investigate the interaction between the electron energy distribution and the dust charging plus recombination process, its influence on the plasma impedance and on the ionization rate. The background gas is argon and a spatial distribution of immobile mono-disperse spherical dust particles is prescribed.
