英文摘要 | The electron emission yields from the interaction of slow highly charged ions (SHCI) He(2+), O(2+) and Ne(2+) with clean Si surface are measured separately. It is found that electron emission yield gamma increases proportionally to projectile kinetic energy E(p)/M(p), ranging from 0.75 keV/u to 10.5 keV/u (i.e. 3.8 x 10(5) m/s <= v(p) <= 1.42 x 10(6) m/s), and it is higher for heavy ions (O(2+) and Ne(2+)) than for light ion (He(2+)). For O(2+) and Ne(2+), gamma increases with Z(p) decreasing in our energy range, and it shows quite different from the result for higher projectile kinetic energy. After calculating the stopping power by using TRIM 2006, it is found that the fraction of secondary electrons induced by recoil atoms increases significantly at lower projectile energy, thereby leads to the differences in gamma for heavy ions O(2+) and Ne(2+) between lower and higher projectile kinetic energy. |
