Verified Answer
Which of the statements is true for p-type semiconductors?a)Electrons ...
In a p-type semiconductor, the holes are the majority carriers, while the electrons are the minority carriers. A p-type semiconductor is obtained when trivalent atoms, such as aluminium, are doped in silicon atoms.

Understanding P-Type Semiconductors
P-type semiconductors are essential in the field of electronics, particularly in the construction of diodes, transistors, and integrated circuits. The following key points explain why option 'D' is the correct choice:
Majority and Minority Carriers
- Holes as Majority Carriers: In p-type semiconductors, holes (the absence of electrons) are the primary charge carriers. They are created when trivalent atoms, which have three valence electrons, are introduced into the semiconductor material, typically silicon.
- Electrons as Minority Carriers: Although electrons exist in p-type semiconductors, they are considered minority carriers because their concentration is lower compared to holes.
Doping Elements
- Trivalent Atom Dopants: P-type semiconductors are doped with trivalent atoms, such as boron or aluminum. These atoms have one less valence electron than the silicon atoms they replace, resulting in the formation of holes.
- Pentavalent Dopants: Contrarily, pentavalent atoms (like phosphorus) are used to create n-type semiconductors, not p-type. These have five valence electrons and donate extra electrons, making electrons the majority carriers in n-type materials.
Conclusion
The correct statement about p-type semiconductors is that holes are majority carriers and trivalent atoms are the dopants. This fundamental understanding is crucial for grasping the behavior of semiconductors in various electronic applications.
