Abstract

The mobility of ions plays an important role in the theoretical analysis of many phenomena in low-temperature plasmas, such as ambipolar diffusion, the formation of electrode and surface sheaths in gas discharges, particle charging and the ion drag force in dusty plasmas. A modification of the semiempirical Frost formula for the mobility of positive atomic ions in their parent gases is proposed. The modified expression demonstrates excellent agreement with experimental results for various ionized rare gases in a very wide range of electric field strengths and temperatures.

稀有气体在母体气体中的原子迁移率的近似值

摘要

离子的迁移率在低温等离子体中许多现象的理论分析中起着重要作用,例如双极性扩散,气体放电中电极和表面鞘的形成,颗粒带电以及多尘等离子体中的离子阻力。建议对正原子离子在其母体气体中迁移率的半经验弗罗斯特公式进行修改。在很宽的电场强度和温度范围内,修饰的表达式与各种电离稀有气体的实验结果显示出极好的一致性。
