Both silicon and germanium have the diamond crystal structure, in which each atom is bound to four neighbours by covalent bonds. Since both elements are quadrivalent all the available valency electrons are utilized in the formation of these bonds, the first Brillouin zone is full and, as in the case of diamond, the crystal in the pure state is an insulator. Suppose, now, that a small quantity of arsenic is added to...
