Question:
What is the name of the level formed due to impurity atom in $p$-type in the forbidden gap?
What is the name of the level formed due to impurity atom in $p$-type in the forbidden gap?
Updated On: Jun 14, 2022
- Donor level
- Acceptor level
- Conduction level
- Forbidden level
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
In $p$-type doping, the impurities have left holes in the atomic structure which tend to attract and hold free electrons; This pulls the fermi level down until it gets close to the valence bond. Hence, name of level formed due to impurity atom is $p$-type in the forbidden gap is acceptor level.

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.
