That's why you are in IIT sir... Wonderful lecture & Amazing style of imparting knowledge into young minds... 👏👏

Very nice explanation Sir. I wish we got teachers like you in every Indian University.

14:26 in the last second row 4th column boy looking at the red t shirt girl😎😆😆🤩

No words to say....I don't know which word will be better to express this great teaching.....but one word ....thankyou...for your work

This lecture is just out of the world

Sir Your English and your explanation is so simple and very very clear. Seriously good explanation . We love to here from you sir .... Lots and lots of thanks .. Happy teachers day...

Extremely logical and clear, thank you so much!

Wish all my lecturers at undergrad were this good because only now in my 1st year of PhD, I understand lol

the best in the business. Amazing lecture sir

Awesome expalnation for energy band...helped me a lot.

Excellent material. Thanks for sharing

Amazing lecture! Thank you!

Simply amazing learning these ...

Easy to understand. Thank you for this lesson.

I just can say woooooooooow guy you are an amazing solid state teacher. I have to thank you man thank you

Thanks, a very good explanation, I now understand the concepts much easier

sir amazing lecture you have given

I am in Msc physics, due to pandamic all my proffesors take online lectures but they are Just reading the pdfs or their ppts not explaining anything at all and just read and go, Thank god to this lecture, almost 7 units i have understood using ntpel lectures.😄 Hope my proffesors learn to teach like this.

Clearly explained.. thank you sir

Sir you are an amazing teacher

Brilliant!! makes SOOO much sense, thank you!!

damn,I really understood origin of bands .thank you sir!!

Thank you Prof. 🏆

Thank you so much proffesor❤️🎉

All doubts cleared :) Thank you

amazing very helpful thnx a lot

very good explanation, sir. thank you

amazing lecture and could be more awesome if the video quality is increased...

We have the continuous values of potential which depends on the distance of the electron from the nucleus. Then how come the energy values are quantized?

Enjoyable lecture.

I really appreciated this lecture - thank you very much !

wow what a nice classroom, looks comfy!

At 23:10, we get E_n by considering both potential and kinetic energies, don't we?

I know he's out of chalk after each lecture. This is taught well.

شكراً جزيلاً.

Great!!

thank u soo so much sir.....

Thanks a lot teacher.May Allah bless you

When interatomic separation reduces, electrons in the outer orbitals of two atoms tries to attain a exact quantum states (have same E, identical spin). As per pauli its not possible, so gives birth to new orbitals (Bonding and antibonding ) by splitting of energy bands. While electrons occupies the bonding molecular orbitals (valence band) are bonded to the nucleus tightly leads to energy reduction (VB-lower energy states) and electrons who doesn't have bonding partners occupies antibonding molecular orbitals (Conduction band) which is of higher energy states (since bonding always reduces the free energy gets the stable arrangement). As you decrease the interatomic separation (per say 2 Si atoms), (3p) outer orbitals in those 2 atoms gets close to each other (less splitting) and even decrease further more inner orbitals (2p,3s) of these two atoms get close to each other results in splitting of quasi energy bands (high splitting) have discrete QM allowed energy values. Due to again PAuli priciple, no 2 electron can have same set of 4 quantum numbers

Is this splitting is for one atom ?

Energy splitting takes place when the interatomic spacing of TWO ATOMS are decreased...

Enlightening lecture sir!

Thanku thanku 👌

Shit. That energy level diagram has given me a good understanding of energy levels. I have never seen it like this in my university lectures. 34:00

Thanks

Wow!!

At 21:00 of the lecture, corresponding to each and every V, there is one possible energy Eigen Value or set of Eigen Values?

that's how one should teach, the first time I got to understand this entire band theory concept.

Great lecture led by Great professor - I can't make out how the students are seated in the classroom though...seems different group of people are sitting against the same wall! Are they real audience or PS from other clips??? LoL.

If the levels are splitted then what about the formula that radii varies as n^2? I mean to say there are 5th orbit is splitted into 10s! Will all of their value be 5^2??

Elegant Explanation !

Volume of unit cell = 125*10^-24 CC One unit cell has 8 atoms. So how many atoms will be there in 1CC? 125*10^-24 = 8 1 = X X comes out to be 6.4*10^22. Why sir is getting 0.8*10^22?

@Dkgupta121

Krishna Khandelwal In simple cubic, 1 unit cell has only one atom because one atom at each corner of unit cell is equally divided between 8 unit cells, therefore each unit cell gets only 1/8th part of this atom. And as there are 8 corners in a unto cell so total number of atoms in a unit cell = 8*1/8=1 atom
