$p-$type

Vedclass · Answer

(B) Silicon $(Si)$ belongs to group $14$ of the periodic table,which has $4$ valence electrons.Boron $(B)$,Aluminum $(Al)$,and Gallium $(Ga)$ belong to group $13$,which has $3$ valence electrons.When $Si$ is doped with group $13$ elements,there is a deficiency of one electron in the crystal lattice,creating an electron hole.Since the charge carriers are positive holes,the resulting semiconductor is a $p-$type semiconductor.
