Assertion: Electron has higher mobility ...

Assertion: Electron has higher mobility than hole in a semiconductor.
Reason: Mass of electron is less than the mass of hole.

A

If both assertion and reason are true and the reason is the correct explanation of the assertion.

B

If both assertion and reason are true but reason is not the correct explanation of the assertion.

C

If assertion is true but reason is false.

D

If the assertion and reason both are false.

Text Solution

Verified by Experts

The correct Answer is:
A
The ratio of the velocity to the applied field is called the mobility. Since electrons are lighter than holes, they move faster in applied field than holes.
