Semiconductor: What is Intrinsic and Extrinsic Semiconductor ? P-Type and n-Type Semiconductor

In this video, the semiconductor basics have been explained.
By watching this video you will learn the following topics:
0:54 Types of material: Conductor, Insulator and Semiconductor
2:29 Basics of Semiconductor and the concept of holes and electrons in the semiconductor
6:06 Intrinsic and Extrinsic Semiconductor
7:00 p-type and n-type semiconductor
The semiconductor materials like Silicon, Germanium, and GaAs are widely used in the electronics industry for making electronic devices like a diode, transistor, and other integrated circuits.
In terms of the conductivity, the conductivity of the semiconductor materials is in between the conductor and insulator.
Conductors like Copper, Silver has very good conductivity.
While insulators like Dry wood, rubber, mica have very poor conductivity. But the conductivity of the semiconductor is in between the conductor and insulator.
Moreover that in semiconductor, by adding the external impurities, the conductivity can be changed. And this property is mainly used in manufacturing various electronic devices.
Unlike conductor, in semiconductor, there are two types of charges which contribute in the flow of current.
1) Electrons
2) Holes
And by adding the external impurities the concentration of electrons and holes can be controlled.
The semiconductors can be classified into two categories
1) Intrinsic Semiconductor
2) Extrinsic Semiconductor
In the intrinsic semiconductor, no external impurities are added. And the concentration of holes and electrons is equal at the given temperature.
In the extrinsic semiconductor, the external impurities are added. And further depending on the type of external impurity, the extrinsic semiconductor can be classified as
1) p-type semiconductor
2) n-type semiconductor
p-type semiconductor:
In the p-type semiconductor, the trivalent impurities like Boron, Aluminum, and Gallium are added to generate the excessive holes.
n-type semiconductor:
In the n-type semiconductor, the pentavalent atoms like arsenic, antimony and phosphorous are added to generated the excessive electrons.
This video will be helpful to all the students of science and engineering in understanding the basics of the semiconductor.

Nice explanation. But in diagrams of P and N-type blocks displayed in the rare end of the video should have little corrections in N-type No of electrons should be equal to a sum no. of hole and no. of immobile positive ions.

[@sushmanaik2228]

Thank you sir, Sir,Does ions helps in conductivity or it is neutral?when two charges combine together will it form an ion(acceptor ion formed due to hole in p type filled with electron)?

[@raghavendranileha1059]

Actually.....The ions r fixed in the valence shell(as they r involved in bonding)...So they only produce an electric field for the charge carriers to move... Hope this answer helps....😃

[@SonuSharma-gy6iw]

Why acceptor ions is specified as negative and donor ions as positive.

[@ALLABOUTELECTRONICS]

Becuase to complete the valency, the acceptor atom needs to accept one electron. By accepting one electron the net charge is negative. Similarly, by donating one electron, the donor atom completes the valency and becomes an ion. As it has donated one electron, so the net charge is positive. I hope it will clear your doubt.

Why does conductivity depend only on electrons in conductors but in semiconductors depends on holes and electrons? bcoz even in conductors when electrons will leave its position a hole would be created as in semiconductors??

sir, I'm having following doubts, please do clarify. 1.how much charge an hole have? 2. how come an hole can move as being in covalent bond? 3.why can't electron and hole can move without external filed( external voltage source), as per coulombs principle ( charges have force on each other)? 4. what is the difference between electron and anion & hole and cation( interns of charge and behavior and all. )
