Question

Electrical conductivity of a semiconductor

• A. Decrease with the rise in its temperature
• B. First increases and then decreases with the rise in its temperature
• C. Increase with the rise in its temperature.
• D. Does not change with the rise in temperature.

Hint:

Semiconductors exhibit increased conductivity with rising temperature due to the increased excitation of electrons.

Answer 1

The Correct Option is C

\nIn semiconductors, conductivity grows with temperature because more electrons gain enough energy to move from the valence to the conduction band, increasing conductivity.
