Which of the following statements is true about p-type silicon?
A) Electrons are the mobile charge carriers.
B) It is produced by doping Si with P or As.
C) It does not conduct electricity as well as pure Si.
D) All are true.
E) None is true.

Question

Quizplus · Accepted Answer

P-type silicon is created by doping silicon with elements such as boron or gallium, which have one less valence electron than silicon. This results in holes being the mobile charge carriers, not electrons, making statement A incorrect. Statement B describes n-type silicon, not p-type. Statement C is also incorrect because the introduction of holes (positive charge carriers) in p-type silicon improves its electrical conductivity compared to intrinsic (pure) silicon, though the context of "as well as" could be misleading without specifying the type of conductivity being discussed (intrinsic vs. doped).
