Question

P type semiconductor

Answer 1

In p-type semiconductors, holes are the majority carriers and electrons are the minority carriers. P-type semiconductors are created by doping an intrinsic semiconductor with acceptor impurities (or doping an n-type semiconductor). A common p-type dopant for silicon is boron.

Answer 2

the addition of trivalent impurities such as boron , aluminum ,and gallium to an intrinsic semiconductor create deficiency of valency electrons are called holes
