Vedclass · Answer

(A) To produce a $p-$type semiconductor,a group $13$ element (trivalent impurity) is added to a group $14$ element like germanium.$B$ (Boron) belongs to group $13$,while $P$ (Phosphorus),$As$ (Arsenic),and $Sb$ (Antimony) belong to group $15$ (pentavalent impurities).Adding a group $13$ element creates an electron hole,which is responsible for $p-$type conductivity.Therefore,$B$ is the correct dopant.

Which from the following dopants is used in germanium to produce $p-$type semiconductor?
