germanium transistor

基本解释

Germanium was tried because charge flows through it veryrapidly, a key property for a transistor.
之所以选择锗，那是因为电荷流过它的速度非常快，这性质对一个晶体管来说是至关重要的。
The first transistor, created at Bell Labs in 1947, was made of a slab of germanium, an element one spot below silicon in theperiodic table.
1947年，Bell实验室创造了世界上第一个晶体管，该晶体管当时就是用锗板来制备，锗这种元素元素周期表中位于硅的下方。
50 years ago, the first Chinese made alloy junction Germanium PNP transistor was born in the Semiconductor Laboratory of the Institute of Applied Physics, Beijing.
50年前，中国自行研制的第一个晶体管在中科院应用物理研究所半导体器件实验室诞生。
