holes are majority carriers and trivalent atoms are dopants.

Vedclass · Answer

(A) The correct option is $A$.In a $p$-type semiconductor,the material is formed by doping a tetravalent semiconductor (like $Si$ or $Ge$) with trivalent impurity atoms (like $B$,$Al$,$Ga$,or $In$).Since trivalent atoms have three valence electrons,they create a vacancy or 'hole' in the crystal lattice when they bond with the tetravalent atoms.Therefore,holes become the majority charge carriers,and electrons become the minority charge carriers.Thus,option $A$ is correct.
