摘要: 利用Raman和XPS研究N离子注入前后非晶碳膜化学键 合的变化及CN成键情况. 结果表明, 被注入到非晶碳膜内的N与C原子结合, 形成sp3C-N, sp2 C-N 和C≡N键. 随着N离子注入剂量的增加, 膜内sp3 C-N键的含量相对增多, 表明N离子注入更有利于sp3 C-N键的形成.

Abstract: N-implantation into amorphous carbon films with different doses was carried out to study the formation of CN bonding. Raman and XPS sp ectra were used to characterize the chemical bonding of CN bonds in amorphous carbon films after N-implantation. The results show that N atoms implanted into amorphous carbon films are bound to C atoms by different bonding types of sp3 C-N, sp2 C-N and C≡N in the films. When N-implantation dose increases, the relative content of sp3 C-N bonds increases, which is more than those of other types of C-N bonds in the films. It indicates that N-implantation is favorable to the formation of sp3 C-N bonds.

Key words: N-implantation, amorphous carbon film, magnetron spu
