Question

In a p-type semiconductos, which of the following statement is true:

Options

• 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.

Answer 1

Holes are majority carriers and trivalent atoms are the dopants.

Explanation:

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.
