14.2 Which of the given statements is true for p-type semiconductos
(1) Electrons are majority carriers and trivalent atoms are the dopants.
(2) Electrons are minority carriers and pentavalent atoms are the dopants.
(3) Holes are minority carriers and pentavalent atoms are the dopants.
(4) Holes are majority carriers and trivalent atoms are the dopants.
Hint: Recall the p-type semiconductors.
Step 1: Check each option one by one.
In a p-type semiconductor, the holes are the majority carters, while the electrons are the minority carrer. A p-type semiconductor is obtained when trivalent atoms, such as aluminium are doped in siicon atoms.
