E Vs k, Brillouin Zones and the Origin of Bands

[@manojcrisdo247]

Best lecture found on the internet for E-k diagram and Brillouin Zones! Thank you NPTEL

[@MrMGA06]

I never had such an intuitive understanding of this topic though I have a master in theoretical physics. Well done sir. thanks.

[@Noisedown]

Haven't logged in for a while, just logged in because I have to express my gratitude to Dr Haridross for such clear and visual explanation. I learned more in this lesson than in the last month in my solid state physics course. I look forward to watching your other videos.

[@manojhegde9595]

MIT lectures failed to make me understand this so was oxford course notes but you sir have made it 'crystal' clear for me in the first go. Thanks a lot.

[@kjmarjun]

Thanks Dr. Prathap for an excellent way of teaching Brillouin zone.

[@reemreem7043]

I spent months to understand band structure. many thanks doctor

[@creatureofhabit7049]

Absolutely brilliant lecture! Best in the entire world!

[@kat472]

Great explanation mate! I've been struggling with this concept for weeks and you just clarified everything.

[@siddarthshivkumar5780]

Dear Professor, Thanks a lot for your amazing explanation. It really helps me appreciate the subject better.

[@osumj56]

That was a very clear and concise explanation of k-space, and how to construct brillouin zones. Thanks!!!

[@michaelcharalambous3472]

Great presentation...very good, very clear. I clarified confusing issues I had for months. Keep up!

[@DB-ph8pq]

Excellent lecture Sir. One of the best. Explains many concepts. Thank you for your effort.

[@thomasvilayil8708]

Most of my confusions got washed away by your lectures thanku very much ...sir

[@anaghaanilkumar5879]

Understanding about the topic got really simplified.

[@preranadash9640]

Can you please explain why the energy curve changes for diffraction?

[@ratulbiswas1812]

Respected Sir, it was an awsome lecture.......Thank you for such an awsome lecture

Excellent. I would explain it the same way and this is how it should be done. Respect. I am glad to see someone who likes to really teach.

[@ajayan123456789]

a very good video... thank you for the lecture Professor.

[@sphericalcow3143]

This is a spectacular lecture! Thank you for clearly explaining many key points that other professors and text books often fail at. I also have a question for you. Why can the origin in reciprocal space be located at any reciprocal lattice vector? If a wave function has a wave vector equal to any reciprocal lattice vector, does it have an energy of 0?

[@alfazbagawan3088]

Best lecture Sir. Very keenly explained each and every term.

[@SimeonHanks]

This was very informative and concise! Thank you for such a great lecture.

[@micklegill7678]

I generally don't comment on you tube but after seeing this. WOW!!!!!!!!

[@Geo877]

Really fantastic teaching. Thank you very much!

[@engwenong5160]

You, sir, are a genius. Thank you!

[@Oydle]

Thank you so much for making this video. This has helped clear a lot of things up for me!

[@suzieanddusty]

What is the mathematical relation that governs the broken graph for electron energies due to interaction with lattice points and what really is happening that frobids certain energy values?

[@bismaimran8114]

Thank you so much for such a wonderful explanation of the topic.

[@sianacademy2560]

Bisma Imran welcome

[@adityabhardwaj9136]

@17:39 how Diffraction leads to distortion or how does soem energy value become forbidden ?

[@preranadash9640]

Have you got the explanation of the question you are asking for? If yes please explain me the same

[@shahedriaz132]

I am also looking for an explanation for this

[@alokkumar3703]

thank u sir,almost clearing my doubt of origin of band in solid

[@yxu2973]

great lecture !! this annoying k vector has been torturing me for days. a thousand gratitude, thank you, sir!

[@chaudry123]

Very nice lecture I have ever enjoyed. Thanks Doctor

[@somakhanra5221]

Wonderful lecture !!! Thank you very much!!!

[@SunShine-rw3zs]

tankyu sir for ur effort an excellent lecture in all aspects, but I have a question how diffraction lead to distorted in energy and energy gaps.

[@sumankumarnayak2197]

One of the best 😮

[@vinuthasn1677]

One of the best class

[@nenavathparvathalu5012]

Thank you, sir for giving wonderful lecture........

[@vineethbaby42]

Sir, In the Bz boundaries there is no particles are present actually I think. So I have confused with the concept of saying diffraction taking place at BZ boundaries when wave touches there?

[@imeneezzeddine6449]

Thank you so much great explanation!

[@niazikhan8754]

Good lecture....sir plz explain how we can find conduction band and valence band in brillouin zone...plz explian

[@arpitagautam9957]

its relly excellent lecture

[@lionview7953]

such a great lecture

[@dibyajyotidas6947]

you are the best sir

[@gsri72]

Very good lecture ...

[@tamannaakter2250]

Alhamdulillah, a good one

[@saumyashreebaral9823]

Can we take more than one origin at a time ?

[@debajyoti.guha_bong]

Thank You sir. You are very good.

[@somnathchavan9909]

What is bound electron???

[@thismeetup8173]

Thank you 😊

[@sharanjitsandhu2445]

Really helpful

[@bipulhimansu4225]

perfect explanation

[@nepalji2123]

You are hero...sir...

[@wahidurrahman7392]

thank you sir..

[@seema4337]

sir can u make video on extended,reduced,periodic zone scheme

[@ranjankumarsahu998]

seema nooli see the whole video
