Question

Write down 5 difference between N-type and P-type semiconductors.

Answer 1

Difference between the P and N type semiconductors

Sl No	P-type Semi conductor	N-type semi conductor
1	P-type semiconductor is formed due to the dopping of III group elements i.e. Boron, Aluminium, Thallium.	N-type semi conductor is formed due to dopping of Nitrogen, Phosporus, Arsenic, Antimony, Bismoth.
2	These are also known as Trivalent semi conductors.	These are also known pentavalent semiconductor.
3	P-type semiconductors is positive type semiconductor it means it deficiency of 1 electron is required.	N-type semiconductor is negative type semi-conductor it means excess of 1 electron is required.
4	In P-type semiconductor majority charge carries are holes and minority charge carries are electrons.	In N-type semiconductor majority charge carries are electrons and minority charge carries are hole.
5	A hole indicates a missing electron. In this no. of holes is more than the no. of electrons.	In N-type semiconductor the no. of holes is less than the no. of free electron.
