Question:

For a p-type semiconductor, which of the following statements is true ?

Updated On: Aug 16, 2024

Holes are the majority carriers and pentavalent atoms are the dopants.
Electrons are the majority carriers and pentavalent atoms are the dopants.
Electrons are the majority carriers and trivalent atom >re the dopants.
Holes are the majority carriers and trivalent atoms are the dopants.

Hide Solution

Verified By Collegedunia

The Correct Option is D

Solution and Explanation

In p-type semiconductor, an intrinsic semiconductor is doped with trivalent impurities, that creates deficiencies of valence electrons called holes which are majority charge carriers.

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.
