摘要/Abstract

摘要： 利用局域场修正的介电函数,研究了注入离子在强耦合简并电子气中的阻止本领和能量离散。数值结果表明在低速和高r_s值情况下,局域场修正使得阻止本领和能量离散明显地增加。

关键词: 阻止本领, 能量离散, 注入离子, 材料表面改性, 介电函数

Abstract: The stopping powers and energy stragglings for implanted ions in strongly coupled degenerate electron gas were investigated using local-field correction dielectric function.The numerical results have shown thst the stopping powers and energy stragglings were considerably increased due to local-field correction at low volecities and high valuse r_s.

Key words: stopping powers, energy stragglings, implanted ions, material surface modification, dielectric function
