This served me greatly for a final presentation at my Solids State Physics course, thank you. Amazing teacher.

[@SmallFaerie]

Dr Haridoss really explains things extremely well. I use this series as a complement to the lectures in my condensed matter physics course (unfortunately my teacher isn't nearly as good at presenting the material in a structured and easily accessible manner) and I'm so grateful to you for posting this! Thank you! I only grieve that these lectures don't cover the exact same material as my course.

please watch condensed matter physics by manoj harbola satyajeet banerjee nptel lectures available on youtube

[@ibukunolaniyan1072]

One of the best series for understanding solid state physics

Dear Satyajit The energy distribution in temperature is not (and can't be) symmetrical about 0 K. Fermi temperature can be a very high temperature of the order of thousands of Kelvin despite the material having an average of 0 K because the number of free electrons having Fermi energy are extremely small, out of something like 10^23 in the material. So the average temperature will be brought down by rest of the 10^23 electrons and the average will approach zero (not exactly zero, of course). The average temperature just approximates to zero due to electrons which have smaller than Fermi energy. Hope this helps. -Utkarsh

The whole series of lectures is very well explained. Thank you Sir .

please figure out a way to upscale these videos to 1080p

Skeptical about the last assertion that we can rationalize Fermi temperature as a tiny portion having a particular temperature as opposed to the average being 0K. Wouldn't that result in certain electrons with a corresponding negative temperature?

Inspiring lecture, as always..

[@maryjoe9212]

This was very good. Thank you so much for the very clear discussion.

Respected sir,energy can flow in form of radiation but electron is required in case of potential of fermi energy

[@કુલદિપ-છ6લ]

Very well explained 👍😀

[@KhushbookumariRaj-no5xm]

Sir what is "necks" in fermi surface of copper????

[@sribhasmohanta4759]

how chemical potential changes with temperature ? What is the expression of temperature dependent chemical potential ?

[@mohammedsrivastava5917]

Mu=mu(T=0)*(1-(T/Tf)^2) Tf is fermi temperature...mu is chemical potential

Thanks for taking ur time to post this it help me alot

Great lecture! Thanks

[@LetsSmile4Ever]

Thank you for your great lecture. :)

Thanks for this lecture.

Sir, is any higher definition of this video available? Thank you.

Imagine you have a million of something that all equal zero but one equals 1000. Add them up divide 1000/1000000, you have essentially zero still.

大家都说好，可我真的是听不懂这咖喱味儿的固体物理。。我还是自己看书吧QAQ

well Mr. Bat Soup, Good luck with your Wet Market, better stick to live Frogs than Physics

@T 33 how are you so sure that leao jed is the one responsible for spreading corona virus? If it was done by someone else, why are you blaming leao jed for that, since he might have literally done nothing wrong? I really can't understand. One thing that i understand is that you are clearly a racist.
