查询词典 ion-pair

A 2D PIC model was used to simulate the PIII process for a planar target. The simulation results in one whole pulse show that the sheath expands with a decreasing speed and the sheath shape would change form elliptically cylindrical to circularly cylindrical. The dose distribution of ion implantation in the target surface is not uniform, and the concentration depth profiles of retained dose are considerably different, in different positions of the target.

本论文采用二维粒子模拟方法对等离子体离子浸没注入技术进行了模拟研究，在一个完整脉冲时段内，等离子体离子浸没注入平板靶的模拟过程表明：等离子体鞘层的扩展先快后慢，鞘层形状由椭圆柱形向圆柱形演化；注入离子剂量在靶表面的分布是非均匀的；在靶的不同位置注入的离子在改性层中的浓度深度分布有显著差别。
