The effect of ion neutral collision is shown for two species of positive ions in electronegative plasma. The ion neutral collision is modeled using power law of collision cross section. It is a usual case for processing plasma to have two species of positive ions and hence we attempt to study the dynamics of the two species of ions inside the collisional sheath of electronegative plasma.
The aim of this brief report is to study the behaviour of sheath structure in a multicomponent plasma with dust-neutral collisions. The plasma consists of electrons, ions, micron size negatively charged dust particles and neutrals. The sheath-edge potential and sheath width are calculated for collisionally dominated sheath. Comparison of collisionless and collisionally dominated sheath are made.
The aim of this brief report is to study the formation of sheath in a multicomponent plasma. The plasma consists of electrons, positively charged ions, negatively charged massive ions, and beam electrons. It is assumed that the beam electron is ejected from the surface toward the plasma. The sheath edge potential and the floating potential are calculated. Applications of the findings are highlighted.
Using the usual fluid model the behavior of an unmagnetized dusty plasma near a conducting boundary with dust-neutral collisional effect is studied. The plasma consists of electrons, ions, negatively charged micron size dust particles, and neutrals. The Sagdeev potential for collisionless case is also calculated and found that it has different structure for plasmas with and without dusts. An expression for gradient of potential (i.e., the electric field) for collisional dusty plasma with dust–neutral collisions is calculated. The relation between the dust acoustic velocity and the collisionality has been discussed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
