Compound semiconductors can be doped to make n-type andp-type materials, but the scientist has to make sure that theproper atoms are substituted. For example, if Ge were dopedinto GaAs, Ge could substitute for Ga, making an n-type semiconductor;but if Ge substituted for As, the material would bep-type.
