Vedclass · Answer

(B) To obtain an $n$-type semiconductor,pure silicon (group $IV$ element) must be doped with pentavalent (donor) atoms from group $V$ of the periodic table,such as arsenic $(As)$ or phosphorus $(P)$.To obtain a $p$-type semiconductor,pure silicon must be doped with trivalent (acceptor) atoms from group $III$ of the periodic table,such as boron $(B)$ or gallium $(Ga)$.Therefore,for $n$-type and $p$-type respectively,we need to dope silicon with arsenic and boron.

An $n$-type and a $p$-type silicon semiconductor can be obtained by doping pure silicon with
