In the energy band diagram of a material shown below, the open circles and filled circles denote holes and electrons respectively. The material is a/an

A

p-type semiconductor

B

insulator

C

metal

D

n-type semiconductor

Text Solution

Verified by Experts

The correct Answer is:
A
In the given situation the number of holes velence band is greater than number of electrons in conduction band. So it is p-type semiconductor.

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

Assertion: If there is some gap between the conduction band and the valence band, electrons in the valence band all remain bound and no free electrons are available in the conduction band. Then the material is an insulator. Reason: Resistance of insulators is very low

If p is the resistivity of a material, and n is the number density of free electrons in it, the mean time between collisions between electrons in the material is given by: (m denotes the mass of an electron, and e denotes the charge on an electron)
