The energy band gap in semiconductor is:
Correct answer: C. Narrow
- A. Zero
- B. Very high
- C. Narrow
- D. Infinite
Explanation
Semiconductors have a narrow but non-zero energy band gap(typically between 0.2 eV and 3 eV).This allows them to act as insulators at absolute zero but conduct electricity when thermal or electrical energy is applied.

About Physics of Solids
Solids are compared through crystal structure, amorphous arrangement, elasticity, plastic deformation, stress, strain and Young’s modulus. Electrical behavior depends on available charge carriers and band structure, so conductors, insulators and semiconductors must be distinguished from mechanical properties such as strength, stiffness and brittleness.
