Question

Germanium and silicon are called semiconductors. why​

Answer 1

Answer:

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. ... The process of adding these atoms is known as doping.
