Hello guys, Today we briefly discussed the difference between n-type and p-type semiconductors briefly. the total explanation of semiconductors, differences in semiconductors, types of semiconductors, and use of semiconductors, etc.
What is Semiconductor?
Those types of materials are conductivity greater than the non-metal materials but less than the metallic materials. Increasing the conductivity of the material by just mixing the impurities in the materials is called Doping. Pentavalent impurities are added in both n-type and p-type semiconductors.
There are two types of semiconductors:-
- N-types of semiconductors.
- P-types of semiconductors.
What are N types of semiconductors?
The N-type of semiconductor is called an extrinsic semiconductor. It has required the addition of pentavalent impurities for increasing the conductivity of materials like Arsenic, bismuth, antimony, and phosphorus (these materials have five balance electrons). So adding the impurities increase the number of electrons increases (Majority) and holes (Minority) in the semiconductor. The majority of charges flow from the low potential to the high potential.
What are P types of semiconductors?
In P-types of semiconductors have added those elements have three valance electrons in nature. The element used in doping are gallium, indium, and aluminum these are trivalent impurities metals. I have holes in (majority) proportion and electrons in (minority) proportion and charges flow from the high potential to towards the lower potential. The energy level of the acceptor is very close to the conduction band.

The major difference between n-type and p-type semiconductors:-
P-type semiconductor:-
- Hole in the majority and electron in minority.
- for doping use gallium, and aluminum elements for increased conductivity.
- The charge flows from high potential to lower potential.
N-type semiconductors:-
- Electron in the majority and holes in the minority.
- For doping use antimony, arsenic, bismuth, etc for increasing the conductivity.
- The charge flow from low to high potential.
Application of Semiconductor:-
- Mobile phone.
- Embedded Systems
- Computer
