摘要：
The properties of a spherical conductive dust particle on a plasma-facing wall and sheath formation with the dust particle are considered using the self-consistent two-dimensional Particle-In-Cell (2D PIC) simulations. We obtained the self-consistent simulated values of the dust charge on the wall position for different radii of the dust particle and values of the wall potential and made the comparison with the ID model. These results allow us to evaluate the one-dimensional model and clarify the effect of dust shielding by plasma. (c) 2006 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
