The effect of dust charge variation, due to ion flow and electron depletion, on dust levitation
(AIP Conference Proceedings, 2011)
Using a fluid model, the plasma densities, electron temperature and ion Mach number in front of a powered electrode in different plasma discharges is computed. The dust charge is computed using OML theory for Maxwellian ...
Dust particle charge in plasma with ion flow and electron depletion near plasma boundaries
(Physics of Plasmas, 2011-08-01)
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 ...
