ABSTRACT
The charge on micrometer-sized dust particles suspended in plasma above the powered electrode of radio-frequency discharges is studied. Using a self-consistent fluid model, the plasma profiles above the electrode are calculated and the electron depletion towards the electrode, as well as the increasing flow speed of ions toward the electrode are considered in the calculation of the dust particle floating potential. The results are compared with those reported in literature and the importance of the spatial dust charge variation is investigated.

    Self-excited dust density waves in a dusty plasma, containing micrometer-sized particles, have been observed under microgravity conditions at low gas pressures and high dust densities. The waves emerge spontaneously and propagate from the void edge radially outwards to the plasma boundary. We...

    Dusty RF discharges are simulated by using the PIC/MCC method. Secondary electron emissions are taken into account in the framework of the effective yield obtained earlier. It is shown that the secondary emission essentially influence the electron and ion densities in the discharges due to more...
