your style and lectures are best please upload more videos on analog on chapters like filter , oscillator, and other complex topics.

[@mgarg1987]

Very wonderful series of lectures. I have a question. In the last section of this video, the donor atoms are represented by +ve ion and acceptor atoms by -ve ion. Is it true that in n-type semiconductor material, the number of free electrons will be equal to number of +ve ions and in p-type, number of holes equal to number of -ve ions? Thanks in advance....

how can u say some holes in n type and some electrons in p type

[@swamygv1806]

Excellent Presentation very nicely prsented.

[@SAURABHSINGH-xp8dm]

Nicely explained sirr

[@prasadradhika]

I think that the hole should be made along with Boron in the diagram for p-type semiconductor.

[@suhasgogi9394]

Yes, the hole should be along Boron.

[@himanshupratapsingh8997]

Sir what is donor ions you showed in the last segment of the video?

[@shivamrana3800]

They can be si or b

[@electronicsguy8609]

i think there is a mistake at the last part of the vide, in n type, there is supposed to be majourity holes, because trivalent atoms are added, then in the p type there is supposed to be majourity electroncs since pentavalent atoms has been added, please take a look and take us know, if i am wrong please let me know as well. thank you.

[@basavarajant3836]

In n type semicon, pentavalent is doping material, hence e- is charge carrier, and vice versa in case of p-type semicon

[@Fighter_Believer_Achiever]

Thank you very much sir 👏

[@mohdfarmanaliAli]

If we dopped Indium arsenide together what happened or it is possible? Because indium is trivalent and arsenide is pentavalent impurities

[@akashjagtap2784]

What is difference between hole and Positive ion

[@shivamrana3800]

A hole is an empty place where electrons used to stay. It is not a physical entity but helps in making the calculations and understanding concepts easier. On the other hand, ions are atoms that have lost either lost or gained an electron and thus have a charge induced on them.

[@DillonBorges]

Can you explain where the free electrons come from in an intrinsic semiconductor?

[@j4Naga]

due to natural causes

[@thehindupenguin1684]

In an intrinsic semiconductor, the covalent bonds are so weak that they break even at room temperature by absorbing the heat energy from the surroundings. So when the bond breaks, you get the free electron. This is why at absolute zero (0 Kelvin),where there is no heat energy to absorb from the surroundings, intrinsic semiconductors can't conduct electricity because they lack the required energy to break the covalent bonds to create free electrons.

[@alejomeneziii8822]

[@jenithk6769]

How the holes come in n type as minority carrier similarly how the electrons come in p type as a minority carrier?🤔🤔

[@dimitrispalaskas8216]

Due to temperature some electrons gain enough energy to break their covalent bonds , " jump " the energy gap and reach the condaction band. Those electrons leave a hole behind at the atom which they abandoned , hence the holes in n type. In p type , the electrons that broke free(for the reasons mentioned above) are the minority charge carriers.

Hi, I am searching for veriable entered method (V E M) .Please upload it as soon as you can.

[@robertfrostl]

The hole represented in Trivalent doped semiconductor is with the Sillicon atom and not Boron atom. but some books represent it the other way round, like they represent the hole with boron atom and not sillicon atom. Is there any problem? or it is okay with any both the conventions?

[@rohitpathak3574]

Anshul Kumar BRO BOOK WALA CURRECT HAI.... Because hole means electron ki kami and boron has three valance electron...so in fourth covalent bond only si give electron not boron

[@harsh9874]

Which book to follow with these lectures?

[@rangasushma1766]

How the minority charge carries are present? We will have either holes or electrons but how the minority charge carries exist

[@mahesh.khowal]

which ever is less in concentration becomes a minority charge carrier .
