朋友,你知道功能卓越的半导体晶体是怎样诞生的吗?一开始,倘若有人问我这样的问题,我必定一无所知。但就在前不久的阅览课上,我了解到了答案。科学家发现将锗提纯,可以制成极为优异的晶体管。这之后,几乎所有的科学家都为求除尽锗中的杂质,使其纯度达到100%,让理想中的晶体横空出世。 Friends, do you know how a brilliant semiconductor crystal was born? At first, if someone asks me such a question, I must know nothing about it. However, in the recent reading class, I learned the answer. Scientists have found that the purification of germanium can make extremely excellent transistors. Since then, almost all scientists have sought to eliminate the impurities in their doves and have reached a purity level of 100%, allowing the ideal crystals to emerge.
