Vedclass · Answer

(D) To form an $n$-type semiconductor, a pentavalent impurity (an element from Group $15$ of the periodic table) must be added to an intrinsic semiconductor like germanium $(Ge)$.$B$ (Boron), $In$ (Indium), and $Ga$ (Gallium) are trivalent elements (Group $13$), which are used to create $p$-type semiconductors.$P$ (Phosphorus) is a pentavalent element (Group $15$), which provides an extra electron when doped into germanium, thus creating an $n$-type semiconductor.Therefore, the correct dopant is $P$.

Which of the following dopants is used in germanium to form an $n$-type semiconductor?
