Energy Bands in Solids

[@svrbora]

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

[@priyanka__verma]

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

[@Don97-y6i]

This lecture is just out of the world

[@sathishshastry461]

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...

[@002abhishkumarp8]

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

[@vivekpanchal3338]

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.

[@narvirkumargahlawat6915]

Hope you are liking these lectures. your professors too had worked hard to achieve that level. You too can become good one, why not start from yourself...

[@vivekpanchal3338]

[@JCT-]

I just finished MPhil and about to start my PhD. I just understood this topic. Thank you for explaining this to me.

[@polubalaji6761]

Bro.. Can u please explain y the splitting occurs and that too in that y splitting decrese at first and then increse later????

[@alimo166]

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

[@1murkeybadmayn]

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

[@sarthakpant212]

You are awesome man, 1st year in Phd😂😂😂

[@maryamdaneen7190]

Same here

[@notconfirm4492]

Now a days only legends are doing phd

[@ShubhamkumarHota]

the best in the business. Amazing lecture sir

[@Icoronac1]

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

[@vamsimohan5369]

I don't think your name aged well

[@karthicaravind1182]

it is a most historic lecture i am astonished by your lecture, sir thank you sir

[@msrtubetube]

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?

[@deltechdiaries5907]

Sir you are an amazing teacher

[@prabhakarolichannel9747]

what a lecture...!!!! true professor...

[@pratyushpanda8131]

Simply amazing learning these ...

[@mofijulsk2527]

[@anuhermoini1]

superb lecture....u r teaching is very interesting

[@MarceloRodrigues-yx3ty]

Thank you Prof. Shenoy. Excellent class!!!

[@rinucris9562]

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

[@gauravkumar_1626]

Is this lecture for b.tech 1st year students or ...........?????

[@snehashishbanerjee2575]

Both undergraduate and postgraduate

[@roshankharke3725]

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

[@mayur13588]

very good teacher.. Thank you!! Pls upload more

[@vathsalmehta3488]

Is this a 1st year course

[@msrtubetube]

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

[@rakeshyadhuvanshi8405]

Is it for 1st year b. Tech students

[@rakeshyadhuvanshi8405]

Ok if I am watching it

[@rakeshyadhuvanshi8405]

Please Reply as per your knowledge

[@pqpmoscon]

Easy to understand. Thank you for this lesson.

[@ReinventingEducation]

Thank you Prof. 🏆

[@lauraschafer9302]

This is fantastic, great teaching!

[@md.masudrana2593]

great teaching

[@migmartsering1010]

I feel like I am in IIT ...well explained...

[@krishnakhandelwal9466]

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

[@michaelkiffmeier516]

I really appreciated this lecture - thank you very much !

[@dabulls1g]

Seriously, this is an excellent set of lectures

[@sderese]

Thank you very much for simplifying the concept

[@debabratadey923]

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

[@waibenglam756]

Enjoyable lecture.

[@vitthalmishra9325]

Thank you so much proffesor❤️🎉

[@ahmedatifabrar7698]

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

[@rana000]

Is this splitting is for one atom ?

[@snehashishbanerjee2575]

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

[@chuckie5358]

Excellent material. Thanks for sharing

[@arupbiswas8288]

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??

[@mursalayub5167]

Arup Biswas but not required for silicon

[@mohema7083]

Great explanation Many many thanks

[@mukeshmuvva8648]

sir amazing lecture you have given

[@farzanasnigdha7048]

Thanks a lot teacher.May Allah bless you

[@renuka9648]

Clearly explained.. thank you sir

[@polubalaji6761]

Can anyone please explain y the splitting occurs and that too in that y splitting decrese at first and then increse later????

[@vickysathi]

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

[@trentmalone9115]

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

wow what a nice classroom, looks comfy!

bahut achha sir, thanks

[@felipelenzcarvalho]

Amazing lecture! Thank you!

[@chSongCao]

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.

[@Memories_nevver_die]

They r real students.no doubt..

[@snehashishbanerjee2575]

Great observation indeed... I also noticed different students at the same seat in different footages... Looks spooky...lol... But they are real students of IITD no doubt...

[@mahamudurrahaman7069]

Great lecture

[@maryar.5636]

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

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

thank u soo so much sir.....

[@subhajitsarkar3940]

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

[@Jacob-vi2vb]

Great!!

[@marxregis]

Enlightening lecture sir!

[@akashgugnani546]

Elegant Explanation !

[@curiousbit9228]

Wow!!

[@romanibukharst9517]

Thanks

[@kartiksingh4082]

I thought it was for 12 standard ?

[@riseabovehate9476]

Lol. It is for post graduate students.

[@snehashishbanerjee2575]

But some of the parts(fundamentals) u can prefer for 12th preparation... Rest of them are for 1st yr undergrad/postgrad...
