Understanding N-Type Semiconductors

What is the primary characteristic of an n-type semiconductor?

• It is doped with a trivalent impurity.

• It is made of pure silicon.

• It has an abundance of holes.

• It has an abundance of free electrons.

In an n-type semiconductor, what is the role of free electrons?

• They are immobile.

• They are the minority charge carriers.

• They are the majority charge carriers.

• They do not carry any charge.

What happens to electrons when they absorb heat in an n-type semiconductor?

• They become immobile.

• They lose their charge.

• They form a new atom.

• They jump out and leave a hole.

What is the direction of movement for free electrons under an applied voltage?

• Towards the negative plate.

• Towards the positive plate.

• They remain stationary.

• They move randomly.

How do holes move in an n-type semiconductor when a voltage is applied?

• Towards the negative plate.

• They move in a circular path.

• They do not move.

• Towards the positive plate.
