combination of theory and example is so nice

such a great lecture
loved it

[@suniltimilsina6306]

Very Informative. Thank you.

[@tanchienhao]

awesome video!

[@portable7789]

Thanks for the nice explaintation. Could you precise what is the k value at K, W and L position ?

[@konstantinos2818]

Thank you so much, excellent presentation. It is very helpful!!

[@antonpozdeev6370]

Thank you a lot. Very helpful and understandable

[@user-dd7wz6tn3e]

very easy-understanding! thank you

[@ainepo175]

Very good explanation and easy to follow slides! Is there actually a way to access these slides? :)

[@jatinkashyap1491]

Thanks for so good video!

[@libramoon4132]

great very easy method

[@techlim3875]

I always wondered how to connect K to X point. 41:30 explains it, thank you!!! 😂

[@rahuldutta6992]

Why is the dispersion curve flat at the high symmetry points which are exactly at the center between two neighbouring lattices? What is the physical significance of this?

[@adwaitrijal4224]

Thank You!!!

[@SirHiggalot]

In the slide shown around 17:50, why is the point called [100] but it's intersecting on b2, and not b1? Why shouldn't that point be called [010]?

[@abdulchemist9622]

very informative

[@rajmonibasumatary1023]

There are some professors who speak in the lowest volume when a sentence is about to end and people like me can't get the last few words, that makes it difficult for us to understand.

thanks

[@ehanreza6012]

Hello, I am not getting one thing. Why/ How there are six different possible energies in the (Gamma-K) section?
Thanks

[@quantized101]

The unit cell contain 2 atoms, which means 3N=6 degrees of freedom or 6 phonon modes at a certain wave vector. In Gamma-X section, however there are four branches because of degeneracy in transverse acoustic and transverse optical branches.

[@subhendumishra3487]

very bad explanation. Looks like theory is not clear to you.

[@fluxqubit]

@@subhendumishra3487 very bad reply. Just making a general statement, without bothering to add anything useful to the discussion, is not helpful.
