Which of the statements given in Exerciseis true for p-type semiconductors.

Answer»

ELECTRONS are majority CARRIERS and TRIVALENT ATOMS are the dopants.
Electrons are minority carriers and pentavalent atoms are the dopants.
Holes are minority carriers and pentavalent atoms are the dopants.
Holes are majority carriers and trivalent atoms are the dopants.

Solution :Holes are majority carriers and trivalent atoms are the dopants.
A p-type SEMICONDUCTOR is obtained when trivalent atoms, such as aluminium are doped in silicon atoms. In a p-type semiconductor, the holes are the majority carriers, while the electrons are the minority carriers.
