Question

What are the properties of intrinsic semiconductor?

Answer 1

Answer:

1)materials in pure form show the property of semiconductor are called intrinsic semiconductor.

2)the number of free electrons in the conduction band is equal to the number of holes in the valence bond.

3)Its electrical conductivity is low.

4)Its electrical conductivity depends on temperature only.

5)It is of no practical use.

I hope it will help you.

Answer 2

Properties of intrinsic semiconductors are:---

1)They are pure semiconductors with impurities less than 1 and have tetravalent crystals.

2)Presence of mobile charge carriers is intrinsic property of material.

3)No dopping or addition of impurities required.

4) Charges are obtained as a result of thermal excitation.

5)The number of electrons is equal to number density of holes thus are electrical neutral.

6)No permitted energy state between valence shell and conduction band.

7)Electrical conductivity depends on temperature.

8)Their electrical conductivity is low.
