Correct answer is option C.
- P-type semiconductors are created by doping an intrinsic semiconductor with an electron acceptor element during manufacture.
- The term p-type refers to the positive charge of a hole. As opposed to n-type semiconductors, p-type semiconductors have a larger hole concentration than electron concentration.
- In p-type semiconductors, holes are the majority carriers and electrons are the minority carriers. A common p-type dopant for silicon is boron or gallium.
