Physics Question on Semiconductor electronics: materials, devices and simple circuits
For a p-type semiconductor, which of the following statements is true ?
A
Holes are the majority carriers and pentavalent atoms are the dopants.
B
Electrons are the majority carriers and pentavalent atoms are the dopants.
C
Electrons are the majority carriers and trivalent atom >re the dopants.
D
Holes are the majority carriers and trivalent atoms are the dopants.
Answer
Holes are the majority carriers and trivalent atoms are the dopants.
Explanation
Solution
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.
