Answer: Holes.
- A Electrons
- B Holes
- C Both equal
- D Neither
Correct answer: B. Holes
Explanation: P-type is doped with trivalent atoms creating holes (missing electrons). Holes are the majority carriers.
Conductors have overlapping bands, semiconductors have a small energy gap that can be bridged by heat or doping, and insulators have a large gap that blocks conduction.
Concept context
Band theory, p-n junction, diodes, transistors, logic gates, and integrated circuits.
