Silicon and Germanium - HyperPhysics Concepts

Silicon and Germanium - HyperPhysics Concepts

In solid state electronics, either pure silicon or germanium may be used as the intrinsic semiconductor which forms the starting point for fabrication. Each has four valence electrons, but germanium will at a given temperature have more free electrons and a higher conductivity.Silicon is by far the more widely used semiconductor for electronics, partly because it can be used at much higher

Apr 04, 2021 Germanium atoms have one more shell than silicon atoms, but what makes for the interesting semiconductor properties is the fact that both have four electrons in the valence shell. As a consequence, both materials readily constitute themselves as crystal lattices

Why Silicon is preferred over Germanium ? - Engineering

Aug 13, 2016 Although both silicon and germanium are used in semiconductor devices, the present day trend is to use silicon. The main reasons for this are : (i) Smaller ICBO. At room temperature, a silicon crystal has fewer free electrons than a germanium crystal. This implies that silicon will have much smaller collector cut off current ( ICBO) than that

Switch to silicon. Germanium was difficult to purify and had a limited operational temperature range. Scientists theorized that silicon would be easier to fabricate, but few bothered to investigate this possibility. Morris Tanenbaum et al. at Bell Laboratories were the first to develop a working silicon transistor on January 26, 1954
