$B$

Vedclass · Answer

(D) To obtain an $n$-type semiconductor, a pentavalent impurity (Group $15$ element) is added to a tetravalent semiconductor like $Ge$ (Germanium).$P$ (Phosphorus), $As$ (Arsenic), and $Sb$ (Antimony) are all Group $15$ elements and can be used as dopants to create $n$-type semiconductors.$B$ (Boron) is a trivalent element (Group $13$). Adding a trivalent impurity to $Ge$ results in a $p$-type semiconductor, not an $n$-type semiconductor.Therefore, $B$ is the dopant that is $NOT$ used to obtain an $n$-type semiconductor.

Which of the following dopant is $NOT$ used in $Ge$ to obtain $n$-type semiconductor?
