Vedclass · Answer

(A) To produce a $p$-type semiconductor, silicon (a group $14$ element) is doped with a group $13$ element.
Group $13$ elements have $3$ valence electrons, which create an electron deficiency or 'hole' in the crystal lattice.
Among the given options, $Ga$ (Gallium) belongs to group $13$, while $Sb$ (Antimony), $As$ (Arsenic), and $P$ (Phosphorus) belong to group $15$.
Group $15$ elements are used to produce $n$-type semiconductors.
Therefore, $Ga$ is the correct dopant.

Which of the following dopant is used in silicon to produce $p$-type semiconductor?
