( ii ) charging effects on temporal and spatial evolution of dusty plasma sheath in plasma source ion implantation . the temporal and spatial evolution of a dusty plasma sheath in plasma source ion implantation has been investigated with a fluid theory and a self - consistent dust - charging model . a negative potential pulse is introduced to form the plasma sheath ( )塵埃粒子的充電效應(yīng)對等離子體源離子注入( ps )鞘層時空演化的影響采用流體模型及自洽的塵埃粒子充電模型,我們研究了等離子體源離子注入時的塵埃等離子體鞘層的時空演化。
