Answer: Between metals and insulators.
- A Higher than metals in the majority of cases studied
- B Lower than insulators as widely reported
- C Between metals and insulators
- D Equal to metals in standard practice
Correct answer: C. Between metals and insulators
Explanation: Semiconductors have conductivity between metals (good conductors) and insulators. Examples: silicon, germanium.
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.
