At 0 K, a piece of Si has;
Correct answer: B. Empty conduction, and filled valence band
- A. Filled conduction and valence band
- B. Empty conduction, and filled valence band
- C. Empty conduction and valence band
- D. Filled conduction, and empty valence band
Explanation
At absolute zero (0 K), the valence band of silicon is fully occupied by electrons, while the conduction band is empty. This is the fundamental principle of semiconductor behavior and is crucial for understanding its electronic properties.

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.
