Question

Which of the following statement is incorrect about n-type semiconductor?

• A. In p-type semiconductors, holes are the majority carriers and electrons are the minority carriers.
• B. In n-type semiconductors, electrons are the majority carriers and holes are the minority carriers.
• C. N-type semiconductors have a larger hole concentration than electron concentration.
• D. A common dopant for n-type silicon is phosphorus.

Answer 1

The correct option is C N-type semiconductors have a larger hole concentration than electron concentration.

An n-type semiconductor has electrons as majority carriers and holes are minority carriers. Hence electron concentration is more than hole concentration. So (c) statement is incorrect for n-type semiconductors.
