摘　　要：利用金属离子注入技术,将Zn离子注入到硅基上形成一种Zn原子纳米颗粒复合材料.基于太赫兹时域光谱系统,研究该纳米颗粒复合材料在太赫兹波段的传输特性.结果表明,与硅片相比,随着Zn离子注入剂量的增加,太赫兹时域光谱中峰值位置从8 ps分别偏移至7.90、7.98与7.96 ps.通过傅里叶变换,表明Zn离子注入后某些频率处会出现透射增强.By using metal ion implantation technology, Zn ions were implanted into Si surface to form a kind of Zn atom nanoparticle composite. Based on terahertz time-domain spectrum system, the transmission property of the nanoparticle composite was studied at the terahertz wave band. The results show that compared with that of Si, the peak position of the nanoparticle composite in the spectra is shifted from 8 ps to 7.90 ps, 7.98 ps and 7.96 ps with an increase in metal ion implant dose. After the Fourier transform, the transmission-enhanced phenomenon was also observed at some frequency.
