With an increase in temperature, the electrical conductivity of intrinsic semiconductors
Correct answer: A. Decreases
- A. Decreases
- B. Increases
- C. Remain the same
- D. First increases then decreases
Explanation
In intrinsic semiconductors, increasing the temperature leads to more thermal generation of charge carriers (electrons and holes), which results in increased carrier concentration and, consequently, increased conductivity.

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.
