Influence of multi-ion on the dust grain surface potential of complex plasmas using non-Maxwellian approach

Dust grain surface potential in multi-ion plasmas having two negative ions within the context of kappadistributed dusty plasma is studied analytically and numerically. The plasmas current equations Xe+-F- -SF6- and Ar+-F- -SF6- solved using the typical parameters of laboratory multi-ion plasmas and attained dust grain surface potential strongly depends on the plasma parameters for example kappa, density, and temperature ratios. The dust grain surface potential displays the non-monotonic behavior for values of the kappa, temperature ratio and for changed values of density ratios in the framework of both Xe+-F- -SF6- and Ar+-F- -SF6- plasmas. Additionally, the temperature ratio effect is minor on the dust grain surface potential. Our results show that considering the broad variety of Xe+-F- -SF6- and Ar+-F- -SF6- masses is of great importance and advantageous for the analyses of plasma physics, particularly the physics of multicomponent plasmas.

Automated summary

The study focuses on the dust grain surface potential in multi-ion plasmas with two negative ions within the context of kappadistributed dusty plasma. Results show that the dust grain surface potential strongly depends on parameters like kappa, density, and temperature ratios. The behavior of dust grain surface potential exhibits non-monotonic trends and is minimally affected by temperature ratios. Considering a variety of Xe+-F- -SF6- and Ar+-F- -SF6- masses is important for the analysis of plasma physics, especially in multicomponent plasmas.
