Effect of the reduced electric field (E/N) and species concentration on the electron transport properties in Cu-Ne plasma mixture
摘要
This study explores the influence of the reduced electric field (E/N) and species concentration on electron transport properties in a copper-neon (Cu-Ne) plasma mixture. A numerical model is employed to compute key electron transport parameters, including the total collision frequency, momentum transfer frequency, momentum frequency of electrons and ions, and energy mobility. These parameters are analyzed for copper concentrations from 0.001 to 0.5 mol and reduced electric field values between 1 and ~20 Td. The electron energy distribution function (EEDF) is also calculated for each condition. The results demonstrate that increasing the reduced electric field significantly raises the average electron energy, resulting in notable changes in transport coefficients. Moreover, variations in copper concentration alter collisional dynamics and energy transfer processes, primarily due to the distinct collision cross sections of Cu and Ne atoms. The outcomes of this study provide valuable insights for optimizing plasma conditions in applications such as plasma processing, lighting technologies, and pulsed discharge systems. Additionally, the findings offer a useful reference for future research on multicomponent plasma systems involving both noble gases and metallic species.
