半导体元素——锗和硅——在新技术的发展上是非常重要的,这就引起了广大读者对这些元素的制取和利用途径方面的兴趣。这些元素的半导体性能因杂质的多寡和杂质的类型而变。杂质的影响极大,10~7—10~8个原子中有一个杂质原子就会增加了半导体的导电率。这就是说,有待科学家研究出半导体元素的有效纯化法以制出高纯度的半导体材料。半导体已经知道的和预期的用途在报章杂志上已经谈得相当详细了,但是关于制取半导
The semiconductor elements - germanium and silicon - are very important in the development of new technologies, which has aroused the readers’ interest in the preparation and utilization of these elements. The semiconducting properties of these elements vary depending on the amount of impurities and the type of impurities. The impact of impurities is extremely large. One impurity atom in 10 ~ 7-10 ~ 8 atoms will increase the conductivity of the semiconductor. That is to say, pending the scientists to study the effective purification of semiconductor elements to produce high-purity semiconductor materials. The already known and intended use of semiconductors has been discussed in considerable detail in newspapers and magazines, but with regard to the preparation of semiconductors
