Which of the energy band diagrams shown ...

Which of the energy band diagrams shown in the figure corresponds to that of a semiconductor?

A

B

C

D

Text Solution

Verified by Experts

The correct Answer is:
D
In semiconductors, forbidden energy gap between the velence band and conduction band is very small, almost equal to `kT`. Morever, velence band is completely filled where as conduction band is empty.
