Vedclass · Answer

(D) Silicon $(Si)$ belongs to group $14$ of the periodic table,while boron $(B)$ belongs to group $13$.When silicon is doped with boron,boron atoms occupy some lattice sites of silicon.Since boron has only $3$ valence electrons,it creates an electron deficiency or a 'hole' in the crystal lattice.This electron-deficient site acts as a positive charge carrier,resulting in the formation of a $p$-type semiconductor.

Doping of silicon $(Si)$ with boron $(B)$ leads to:
