CHARGING PROCESS OF A NANOPARTICLE IMMERSED INTO PLASMA CONSISTS ( Ar+, SF^-6, an‎d ELECTRONS)

This research presents a computer study to simulate of charging process for a nanoparticle (radius =50 nm) immersed into plasma contain electrons, positive ions (Ar+), and negative ions (SF^-6) (The mass of negative ion approximately heavier than the mass of the positive ion), and studies statistical fluctuations of a nanoparticle charge with time. The research also appears effect of negative ion density on charge of nanoparticle.
