Which of the following elements would be added to germanium to produce an n-type semiconductor?

Question

Quizplus · Accepted Answer

Arsenic is added to germanium to produce an n-type semiconductor. This is because arsenic has five valence electrons, one more than germanium, which has four. When arsenic atoms replace some of the germanium atoms in the crystal lattice, the extra electrons from arsenic contribute to electrical conductivity by providing additional free electrons, which are the majority charge carriers in n-type materials.
