Decoupling of dust cloud and embedding plasma for high electron depletion in nanodusty plasmas

Abstract In recent years nanoparticles have become key technological products, e.g., as coatings with tunable optical gap in third generation solar cells, nanocrystals for photonic applications, and pharmaceutical nanocarriers. particle sources, that use reactive, nanodusty plasmas, a high dust density changes the properties of dusty plasma compared to free considerably, electron depletion leads reduced number electrons. This is called Havnes effect was central understanding famous spokes Saturns rings. We see here, it also important applications. Using self excited waves (DDW) diagnostic tool, we completely characterize an argon discharge embedded amorphous hydrocarbon different size density. The results show, governs charge grains, while particles has only weak influence. ion electric potential profile are almost independent both, well suggests, rf generated cloud seem coexist coupling both weak.
