Zn掺杂n型硅材料的补偿研究
Compensation Study of Zn Doped n-type Silicon Materials
【摘要】 为了获得不同补偿度的硅材料,采用高温气相扩散的方法,在n型硅中掺杂深能级杂质Zn,得到各种电阻率(在25℃下)的补偿硅。实验表明,对具有不同初始电阻率的硅材料,扩散后电阻率随扩散温度和杂质投入量的不同都有较大变化,而且随杂质投入量的增加,电阻率都有一个急剧变化的转折点。
【Abstract】 In order to obtain compensated silicon having different compensation degrees, deep level Zn impurities were doped in n-type silicon using high temperature gaseous diffusion method. Compensated silicon materials having various resistivities (at 25℃) were obtained. It is show that resistivities after diffusion vary significantly with the increase of diffusion temperature and the quantity of diffusant for the materials having different initial resistivities. There is a turning point, where resistivity varies rapidly with the increase of diffusant quantity.
