Solution

Difference between the P and N-type semiconductors.
No.
P-type Semiconductor
No.
N-type semiconductor
(1)
The p-type semiconductor is formed due to the dopping of III group elements i.e., Boron, aluminum, sodium, Thallium.
(1)
The n-type semiconductor is formed due to dopping of Nitrogen, Phosphorus, Arsenic, Antimony, Bismuth.
(2)
These are also known as Trivalent semiconductors.
(2)
These are also known as pentavalent semiconductors.
(3)
P-type semiconductors are positive type semiconductor it means it a deficiency of $1$ electron is required.
(3)
The n-type semiconductor is negative type semi-conductor it means an excess of $1$ electron is required.
(4)
In P-type semiconductor majority, charge carriers are holes and minority charge carriers are electrons
(4)
In N-type semiconductors majority charge carriers are electrons and minority charge carriers are a hole.
(5)
A hole indicates a missing electron. In this, no. of holes is more than the no. of electrons.
(5)
In N-type semiconductor, the no. of holes is less than the no. of free electrons.
(6)
In this trivalent impurities are added to pure elements.
(6)
In this pentavalent impurities are added to pure elements.
