Why is germanium a good semiconductor? 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. Substituted atoms alter the electrical properties. Which type of […]
