Question:
What controls the conduction of p-n function?
What controls the conduction of p-n function?
Updated On: Jul 27, 2022
- Majority carriers
- Minorty carriers
- Holes
- Electrons
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
On account of difference in concentration of charge carriers in the two sections of p-n function, the electrons from n-region diffuse through, the function into p-region and the holes from p-region diffuse into n-region.

Concepts Used:
Semiconductors
Semiconductors are a crystalline solid materials, whose electrical conductivity lies between a conductor and an insulator. Semiconductors are mainly used in the manufacturing of electronic devices like capacitors, transistors, diodes, Integrated circuits, etc.
Properties of Semiconductor:
- Semiconductor acts like an insulator at Zero Kelvin. On increasing the temperature, it works as a conductor.
- Due to their exceptional electrical properties, semiconductors can be modified by doping to make semiconductor devices suitable for energy conversion, switches, and amplifiers.
- Lesser power losses.
Uses of Semiconductor:
- Semiconductors are widely used in manufacturing electronics devices like transistors, diodes, sensors, integrated circuits.
- Semiconductors are widely used in all electronic devices, like mobile phones, digital cameras, communication devices, trains, ATMs, etc.
